Favorite cover?

As a (minor) film buff, I almost invariably prefer originals. But when it comes to audio, I  have found more than a few covers that I prefer to the originals. So, to kick things off, and with all due respect to Boz Scaggs, I absolutely LOVE this live Incognito version of Lowdown:


What's on the top of your lists?
Dave Edmund's version of Smiley Lewis' "I Hear You Knocking".
Johnny Rivers doing "A Whiter Shade Of Pale"!
bauhaus covering "ziggy startdust" 
Boyce Avenue's cover will be on top of my favorite artists that do an acoustic cover of popular songs.
