Time was, back in the pre-rock era, every song was essentially a cover, in that songwriters would write the songs and performers would sing them. Not so since Elvis, Chuck Berry, Fats Domino, et al., changed music forever. TO BEGIN: Jimi Hendrix created a rather liberal, but effective, interpretation of "All Along the Watchtower" when he recorded it for the 1968 album "Electric Ladyland." What act sang and wrote the song originally?

The Beatles

Bob Dylan

The Doors

Muddy Waters

Joan Baez
