Imagine Rep. Barbara Vucanovich's surprise when she read here yesterday morning that Rep. Lindy Boggs was believed to have become the first great-grandmother in the 201-year history of Congress. Vucanovich was taken aback because she has been a great-grandmother for more than two years and didn't even know that she was the first or that she might be in the running for such a title. Her great-grandson Brendan Erquiaga, who lives in Reno, Nev., was born on Thanksgiving Day 1987.

Boggs wasn't available yesterday to comment on her reduced status, but Vucanovich was pleased. "Reading that I'm the first great-grandmother in the history of Congress makes me feel more grand and less old," she said, "even though I had to wrest the title from my friend Lindy Boggs."

Connick, 22, who was featured on the "When Harry Met Sally ..." soundtrack last year, told the audience that lately he had been writing a lot of romantic songs, and the reason they came to him so easily was because "I'm in love." He had the spotlight turned to where Goodacre was sitting in the front row and asked her to stand up. He leaned over the stage lights and planted a big, audible kiss and then sang a song he had written for her, "She Belongs to Me" ...
