Best rock cover songs, list your favorites

Creedence Clearwater Revival doing; "I HEARD IT THROUGH THE GRAPEVINE".
Might be more of a blues tune, but; Stevie Ray Vaughan doing: Little Wing.

Commenting about Creedence (One of my all time favorites) my wife actually thinks Creedence did a cover of Proud Mary that Ike and Tina Turner recorded.
I must admit both versions are very good.

It's a good cover too.

Steppenwolf's cover of Hoyt Axton's "The Pusher"
Alicia Key's cover of Keith Richard's "Wild Horses"
Adele's cover of Boris William's (The Cure) "Lovesong"

Cassandra Wilson doing Neil Young's Harvest Moon. It makes me shiver when I hear it. I'm not kidding when I say that I'm totally awestruck every time I hear it. Actually, I think that Cassandra Wilson is the best cover artist of all time. She recreates the songs in a way that makes them hers. She is truly amazing. If you're not familiar with her, buy Blue Light Til Dawn and New Moon Daughter. It will be some of the best money you've ever spent on music.
