Jimmy was a genius. He plays a right handed left handed. So the strings are upside down and you downstroke. Not upstroke. I play left handed also. So I always went straight to a reggae or ska strum whenever someone hand a RH guitar to me.
The bass, slightly faster tempo and the vocals make this the absolute best version of this song that I've heard. Pretty good quality recording too. Liked it better than their album version!
