Alan Jackson couldn't go wrong tonight, winning his second entertainer of the year award and four other honors at the annual Country Music Association Awards.

His five awards tied a record for most received in one year. Johnny Cash had that many in 1969, as did Vince Gill in 1993.

Jackson, who was nominated a record 10 times, was also named male vocalist of the year, won album of the year for "Drive," and song and single of the year for his Sept. 11-themed "Where Were You (When the World Stopped Turning)."

An emotional Martina McBride accepted her second female vocalist of the year award after performing her new single "Concrete Angel" for the crowd at the Grand Ole Opry. She also won in 1999.

The Dixie Chicks were named vocal group of the year for the fourth time; Brooks & Dunn took home their 10th award for vocal duo of the year; and Brad Paisley beat out Jackson for music video of the year honors for "I'm Gonna Miss Her (The Fishin' Song)."

The night also signaled the return of Shania Twain to the national spotlight. She added a bit of pop to the show, bounding onto the stage in a black catsuit to sing "I'm Gonna Getcha Good" -- her first network performance since beginning an almost three-year hiatus in 1999, when she was CMA entertainer of the year.

Dolly Parton welcomed the Country Music Hall of Fame's newest inductees -- Bill Carlisle and Porter Wagoner -- with a video montage of their careers.

Country trio Rascal Flatts won the Horizon Award, which goes to a performer or group considered to have good career prospects.

Before the show, Willie Nelson received the vocal event of the year award for "Mendocino County Line," his single with Lee Ann Womack. And Jerry Douglas, who plays dobro with Alison Krauss and Union Station, was named musician of the year.
