Decent Cover versions

[Big Ass Lover]

Camera Obscura covering ABBA's super trooper is the best by far, partly because i don't like abba and they improved it.

The White Stripes covering Dusty Springfields "I Just Don't Know What to Do with Myself is fantastic

Any Elvis song sang by someone else is always 10 times better.

[Arginald Valleywater]

I'll go with Dear Prudence, better than the original.
Far Corps version of Stairway was OK.
Pet Shop Boys version of Village People's Go West.
Rainbow's version of Yardbirds Still I'm Sad.
Deep Purple, Hush.
Aerosmith verson of Beatle's I'm down.
ZZ Tops Viva Las Vegas.
Rod Stewart and Stereophonics versions of Gladrags.....
