Steppenwolf's cover of Hoyt Axton's "The Pusher"

Excellent call Markalarsen. Also "Snowblind Friend" by Hoyt Axton covered by Steppenwolf on Steppenwolf 7.
I personally like a lot of covers and think there is nothing inauthentic about cover versions. For those who think otherwise, I would add: "Girl You Know its True" by Milli Vanilli (inauthentic in so many ways).
In the Air Tonight - Axel Rudy Pell. Recorded very well and the guitar work is outstanding.

Can't have a cover thread without mentioning Imagine & Bridge over Troubled Waters by Eva Cassidy.
