I've agreed to run a charidee pub quiz for the Tsunami appeal and want to do something a bit different for the music round.

What I'm looking for are cover versions of famous songs by other famous artists - I know their are loads of them out there but as the audience aren't likely to be that musically savvy then the songs are gonna have to be pretty mainstream.

For example, I have a Johnny Cash version of a U2 song (One, I think) which is just the sort I'm looking for, but I also have Ben Folds covering Elton John's Tiny Dancer which i can't use because absolutely no-one in the pub except me will know who Ben Folds is.

So any ideas of what i can likely er, acquire, using an un-named popular filesharing program would be greatly appreciated. And remember kids, it's not about how good the tune is, just how recognisable both elements are likely to be...
