There's no such thing as too much Beyoncé. That's apparently the opinion of the producers of this year's Oscar show, who've booked her to sing three of the five nominated songs at the Feb. 27 ceremony. She'll duet with Josh Groban on ''Believe'' from The Polar Express (a song Groban sang alone on the soundtrack), and she'll sing ''Learn to Be Lonely'' from The Phantom of the Opera, a song Minnie Driver sang over the closing credits. She'll even sing the choral tune ''Look to Your Path (Vois Sur Ton Chemin)'' from French film The Chorus, backed by the American Boyschoir. Also on the show, Counting Crows will perform their nominated ''Accidentally in Love'' from Shrek 2, apparently without any aid from Beyoncé. No word on who, if anyone, will sing the fifth nominated song, ''Al Otro Lado del Rio,'' from The Motorcycle Diaries. Still, we like the idea of Beyoncé as utility player; too bad the Academy didn't think of the idea a couple years ago, or they could have brought her in to rap ''Lose Yourself'' in place of no-show Eminem.
