What is your favorite cover?

There are many great covers, such as Mr. Tambourine Man,by the Byrds.  I'm curious about everyone's favorite.


Not exactly a cover as it's Leonard Cohen performing his own song, but with a mind blowing assist by Sonny Rolllins.  Perhaps from David Sanborn TV show maybe 2006.


Susanna Hoffs (featuring Aimee Mann) covering Badfinger’s “Name Of The Game.”

It seems nobody listed "Red Red Wine" by UB40, a Neil Diamond cover.  The story goes UB40 thought they were covering a raggae song by N. Diamond from Jamaica, only to learn later they were covering a white Jewish guy from Brooklyn.  Nothing can beat that.
