I usually prefer versions of songs by the original artist, but there are of course, always exceptions. To me the greatest cover of all time would be Jimi Hendrix’s version of All Along the Watchtower. If we want to note obscure ones as well, I’ll go with Raign’s version of another Bob Dylan classic: Knockin’ on Heavens Door. Any thoughts on a well known one or perhaps an obscure one? As the man likes to say, discuss.
