Covers you like better than the original.
 

I don't remember if we've done this before, but if we have, bite me. :)

Hendrix/watchtower would be the classic example

My fave. The R&B track Tyrone done by My Morning Jacket. This particular performance features Erykah Badu, who's song it is. If you like guitar, hear this through. Love MMJ! You really should check out the entire Red Rocks performance. Two separate shows, completely different, excellent set lists.

At the risk of looking like an idiot, Hendrix's version is the cover?

I really do not remember another version.

How about Judas Priest with the Green Manalishi?

Turn the page - Metallica

This is up there. IMO. Such an emotional rendition:
