Quite appropriate for the holidays I think, Bob Marley's classic "Redemption Song" covered by Johnny Cash and Joe Strummer (late of The Clash)! What a song, what a duet to cover it. Bob's version will always be the best, but this is unique in it's own way...
RIP Bob Marley
RIP Joe Strummer
RIP Johnny Cash
But happy holidays - the message goes on even when the singers are not with us anymore.
