Saw Jeff Buckley and Jose Gonzalez already posted. Can't add to much more. Although I do like A Perfect Circle's cover of Imagine, still like a original a shit load more though.

Serious? I don't like Leonard Cohen's version. The only time it was gun was when it was used in Watchmen. Gun. Best version ever: <iframe width="560" height="345" src="http://www.youtube.com/embed/URxzu8EFBVY" frameborder="0" allowfullscreen></iframe>
