I’m pretty sure it’s John Cale singing in the movie.
A quick search tells me Wainright’s version is on the soundtrack.
I’m down with some nasty bug now and on antibiotics so I may be completely off, but I stand by it being Cale on the movie.
From Wikipedia,
>Cale's version is used in the film Shrek (2001), but Rufus Wainwright's version appears on the soundtrack album.
