Johnny B. Goode
Chuck Berry wrote the classic song, Johnny B. Goode that has been covered by everyone from the Beach Boys to the Sex Pistols and surprisingly enough Peter Tosh. Although it turns out Peter didn't want to do it initially when it was first presented to him, he eventually changed some lyrics a little to make Johnny come from Mandeville, Jamaica and recorded it after the band came up with what is basically a whole new re-write of the music. I think Peter's reggae version kicks ass.
The original and Peter's take on it is here.
