Rufus Wainwright's cover of "Across the Universe" is superb (it's a bonus track on the US release of Poses). Marshall Crenshaw's cover of Grant Hart's "2541" is great (so is the original).

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).
