I got the album Grace by Jeff Buckley about 6 years ago after seeing a documentry on BBC2 about his life..and also the fact that Bradd Pitt really rated him did influence me aswell LOL... I love the title song and most of the other tracks especially Dream Brother and the way he sings the Corpus Christi Carol...it's beautiful.
I don't think that the song in Shrek is by jeff buckley... Bluecat it's Hallelujah but sung buy John Cale (I looked it up in Amazon )
