The ever-growing Grammy show roster of performers grew over the weekend to include a rare TV appearance by Prince, as well as a performance by Beyoncé (who leads the field with six nominations), the Black Eyed Peas (who'll perform their nominated song ''Where Is the Love?'' with Justin Timberlake), and more tribute segments -- to the 40th anniversary of the Beatles' landmark debut on ''The Ed Sullivan Show,'' and to the late Warren Zevon.
Honoring the Beatles (who won only five Grammys during their career) will be an eclectic group of performers, including Sting (who's also performing a duet with Sean Paul during the show), Dave Matthews, Vince Gill, and the Neptunes' Pharrell Williams. Zevon, who died of lung cancer shortly after the release of his album ''The Wind'' last summer, and who's up for five Grammys, will be feted by Jackson Browne, Billy Bob Thornton, Emmylou Harris, Dwight Yoakam, Eagle Timothy B. Schmit, and longtime collaborator Jorge Calderon. The Recording Academy had already announced a tribute to funk music, featuring OutKast, George Clinton, Robert Randolph & the Family Band, and Earth, Wind & Fire.
The Recording Academy also announced it had added Britney Spears, Keith Urban, Kenneth ''Babyface'' Edmonds, and violinist Joshua Bell to the presenters' list, which already includes Williams, Norah Jones, John Mayer, Faith Hill, Aerosmith's Steven Tyler and Joe Perry, Hilary Duff, and actors Sean Astin and Amber Tamblyn. CBS, which is airing the Feb. 8 awards gala, showed an ad during Sunday's Super Bowl that also included Madonna on the Grammy roster, but there's no word from the Recording Academy or from the Material Mom's website of a Madonna appearance at the show.
