'Idol' winner David Cook pays homage to Dave Grohl on 'Tonight Show'

With the contest behind him, American Idol winner David Cook is now paying homage to one of his idols: Foo Fighters frontman Dave Grohl. On this evening's Tonight Show With Jay Leno, after performing his single, "Time of My Life," Cook will play a cover of the Foo Fighters hit "My Hero," one of the band's most beloved songs, which originally appeared on their second release, The Colour and the Shape (the album through which Cook taught himself to play guitar). The exclusive performance is part of the show's Summer Concert Series and will be available online starting at 3:30 a.m.

In a recent interview with Rolling Stone, Cook listed Grohl as one of several rockers on his cowriting wish-list. "The thing I like about him is his music has some substance," Cook said. "He's also kind of realized the absurdity of being a celebrity so he doesn't take himself or any of the extra stuff too seriously. I can only hope to be like that." Cook's full-length debut is scheduled for a November release on RCA Records, the same label that distributes the Foos' albums. No word on whether there's been any official collaboration talks as of yet, but check back for updates.
