Les Savy Fav blew my brain by covering "Precision Auto" by Superchunk to close out their Pitchfork '08 set. Not better than the original, but it was still awesome.

No one's mentioned "Go!" By Tones on Tail as covered by Brainiac, so i'll mention that. Also, i didn't notice anyone mention DEVO's "Head Like a Hole" by NIN.

My pesonal favourites:

Residents - Light My Fire - from Third Reich and Roll - (Doors)

Sun City Girls - Midnight at the Oasis (Maria Muldaur)

US Maple - Lay Lady Lay (Bob Dylan)

Frank Sidebottom - Queen medly

Oh, and The Fall's cover of Day in the Life is a thing of rare beauty indeed.
