This is the best single musical performance I’ve seen on Youtube:
Blue Man Group covering The Who’s Baba O"Riley. I think during the climax they have six drummers/percussionists going at once.
Heart did a couple of very nice covers. I won’t even guess who the original artists are.
Rock & Roll (can’t find it on Youtube)
The Bird and the Bee - How Deep Is Your Love
The Music Machine’s version of Hey Joe preceded Jimi’s. The vocals on this slow version are devastating.
Scott Matthews’ beautiful version of Bob Marley’s Is This Love might be the best cover I’ve heard. I can’t think of a better one.
MiM
Toots & the Maytal’s reggae version of Take Me Home Country Roads puts Denver to Shame
Supernaut– 1000 Homo DJs
Simple Twist of Fate-Concrete Blonde

Led Zeppelin..
Three pages and not one mention of Joe Cocker?
NSYNC is actually one of the most talented groups to unfortunately be labeled a ‘boyband’.
Their tribute to the Bee Gees at the Grammys
I had to revive this thread after I heard this yesterday.
Fleetwood Mac’s “Gypsy” by Gardens & Villa.
Go here to check out my most favorite singer James Otto covering “Into The Mystic” from Van Morrison. 
God bless you and James always!!!

Tom Waits - Heigh-Ho! (The Dwarfs Marching Song)
Here’s a terrific cover of Harvey Danger’s “Flagpole Sitta.” It’s made to sound like a 1960s bubble gum pop song.
That one cracks me up. It is like the Easy E version got highjacked by the glee club.
