It's been a tough couple of weeks for President Clinton. But there's nothing like company to shore up sagging spirits. And last night's star-studded White House dinner for British Prime Minister Tony Blair was just the ticket.

The guest list included Sir Elton John and Stevie Wonder, who teamed up for an after-dinner performance. "It's a bit like playing a wedding reception," John said. Barbra Streisand and her fiance, James Brolin, were there, plus John Kennedy Jr. and Carolyn Bessette Kennedy, Tom Hanks, Harrison Ford, Steven Spielberg, Ralph Lauren, Tina Brown, Anna Wintour, Carol Channing and (whew!) Warren Buffett.

Clearly, it was Clinton's party.

"I'm really pleased the American people have shown great support and good judgment in this matter," Streisand said. "I wish the people who do these illegal leaks and the media who exploit them would show similar respect for the right to privacy and the presumption of innocence. After that, it's no one's business what anyone does behind closed doors."

Not to mention that "he's the most fun president we've ever had -- I think we can all agree about that," said Brolin. "The fact is, the job is getting done and he's enjoying himself."

With 240 guests, it was the largest official Clinton administration dinner held inside the White House. Several guests who originally declined the invitations later scrambled to accept, a testament to Clinton's popularity and the collective star power.

"I can't say we campaigned to come tonight, but we would have," said Sony President Howard Stringer. "It's the ultimate Brit night out." After dinner, he was even more impressed: "If it gets any cooler than this I'll be frozen."

Even a "not too social" fellow like Senate Majority Leader Trent Lott couldn't refuse. "My wife would kill me if I tried to skip an event like this," he said.

This is the first real baby-boomer White House dinner: Clinton, 51, and Blair, 44, both have boyish good looks, Oxford educations, wives who supported (emotionally and financially) their political careers and a passion for popular music.

And so it was no surprise that they bonded so quickly. The Clintons went to London shortly after Blair's victory last May, but this is the prime minister's first official visit to Washington.

The official agenda: Iraq, Bosnia, Northern Ireland and NATO expansion. The unofficial agenda: proof that it's business as usual at the White House. Pundits speculated that Blair was serving as a "human shield" for Clinton, a charge the prime minister flatly denied. "I don't regard myself as doing a favor at all," he told ABC television earlier this week. This visit had been scheduled before the allegations of hanky-panky with a former White House intern hit the headlines.

The mere presence of John and Wonder was enough to assure a memorable evening. "Two of the world's greatest entertainers are here," said presidential pal Harry Thomason. "So being in the entertainment business, how could you go wrong?"

"Everyone's really buzzing," said designer Lauren. "It's really exciting."

"I'm excited," said presidential adviser James Carville. "It's fun to call everybody afterward and tell them what it was like."

This was the second White House dinner in a row for Spielberg, who was a guest at October's fete for China's Jiang Zemin. There, he said, he felt like Forrest Gump. This time, "I brought Forrest Gump," he said, pointing to Hanks.

As one might expect with such an array of star power, there was quite a display of fashionable attire. Hillary Rodham Clinton's gold lace gown by Pamela Dennis complemented the gold dinner suit of Cherie Blair.

Bessette was sleek and elegant in a black fitted gown. Streisand designed her own empire-waist burgundy velvet dress. Diane von Furstenberg fluttered in a navy ostrich boa. But it was Channing, who has traded her trademark blond hair for a salt-and-pepper do, who caught everyone's eye with tinted glasses, rhinestones and a gaudy, sparkling choker.

The toasts before dinner were long on charm and laughs and short on diplomatic pontificating. Clinton began by acknowledging the "uncommon friendship" between the two nations. "In honor of your visit," said the president, "the place where you and Cherie are staying will now forever be known as Blair House" -- a line that drew a big laugh from the guests.

Blair's tribute began on an equally lighthearted note, but the prime minister went on to affirm his friendship with Clinton: "Bill, I'm pleased to call you a good colleague and proud to call you a good friend. I know I'm not alone in supporting you. I know the American people support you, too." There was sustained applause from the audience, then Blair went on to praise the first lady as well.

To reflect the "warm" relationship between the two countries, Hillary Clinton decorated the East Room in tones of gold, peach and terra cotta. She selected a menu of honey-mango glazed chicken, grilled salmon fillet "mignon" with portobello mushrooms, and marinated fresh mozzarella (a favorite food of Blair) served with roasted artichokes and basil tomatoes. All the wines were from Napa Valley but had ties to England.

Dessert was a spectacular chocolate basket filled with strawberry mousse, served with fresh strawberries and chocolate figures of London's Big Ben.

After dinner, the guests swept into a tent erected over the West Terrace for the entertainment. Wonder sang for the Clintons at the 1997 inaugural gala, but John was performing at the White House for the first time.

"I've loved Stevie Wonder since I was 9 years old -- he's my hero," said Melissa Mathison, screenwriter and wife of actor Harrison Ford.

There was a rumor that the two rock-and-roll leaders -- Clinton with his saxophone and Blair strumming a guitar -- might join the musical legends onstage. But the White House sadly announced no instruments had been requested for what would have been a historic jam session.

"It's a pretty high-powered battle of the bands either way," Hanks said. The hour-long concert began with John performing "Your Song." After he finished, the singer said he was so nervous that he had forgotten to greet the distinguished guests and proceeded to do so. He then launched into a series of his greatest hits: "I Guess That's Why They Call It the Blues," "Daniel," "Can You Feel the Love Tonight" and "Don't Let the Sun Go Down on Me."

After John introduced him as "one of the all-time great musicians," Wonder took to the piano. He paused. "Just looking at everybody," the blind musician kidded.

He launched into a version of "Overjoyed" by saying, "This song probably describes how I feel about this night. Check it out."

Wonder tried to inject a little life into the audience by asking them to clap while he sang "For Once in My Life." Throughout his performance, he teased, prodded and cajoled the crowd of luminaries. "Snap your fingers, shake your head. Do some thing!" he pleaded. "You guys sound like a library meeting."

After "I Just Called to Say I Love You," a selection which elicited some snickers from the press corps, Wonder continued with "Sir Duke," "Isn't She Wonderful" and, in honor of Mrs. Blair, "My Cherie Amour," which drew an appreciative laugh from the audience.

Sir Elton joined Wonder on stage for the final song, which Wonder introduced by saying that "love was wonderful, but when you can't get the love, this is what you ask for." The two then jumped into a rousing rendition of "Money Money."

They received a standing ovation, of course. Clinton added his appreciation. "Thank you, Sir Elton," he said. "I wish I could give Stevie a knighthood."

But the party wasn't over yet! The president, first lady and guests danced to "My Girl," "Mustang Sally," "Heard It Through the Grapevine" and "In the Mood." The Clintons had such a good time they stayed until 1 a.m.

"It's like the wildest wedding I've ever been to," said Hanks, as the party drew to a close. "Good band, good food."

A good time for the president -- for a few hours, at least.
