There are a couple of Mashup sites that I hang out at and poach tunes from. One of the message boards sent this along. It's George Bush "singing" the tune written by U2. You can stream it or download it.
While I'm at it, let's pass along this link to a tune from William Shatner's upcoming album (release date is October 8th). The album is produced by Ben Folds and features him as well as Henry Rollins and Joe Jackson on vocals. Oddly enough, this is a pretty good tune.
