Ha! slaw’s Richard Thompson cover of "Oops!...I Did It Again" is genius! Fun topic. And djones51’s The Band’s "I Shall Be Released" is one I wish I had made (maybe I did in the similar thread?). Richard Manuel’s falsetto vocal is really special. For another great version of his Janis Joplin's "Me And Bobby McGee", give a listen to Gordon Lightfoot's recording. ARC's Bill Johnson really liked the recorded sound quality of the album it's on (If You Could Read My Mind) too. 

Talking Heads. Take me to the River. Jimi Hendrix. All Along the Watchtower.
