Frank Zappa is a musical legend and has a very loyal following. He passed away December 1993, but his music and compositions live on forever. Frank Zappa also was a champion of the First Amendment and fought all kinds of Music censorship. He had strange allies with Donny Osmond and a few others when it came to ratings on records. His solution was to have the lyrics available to parents, which made a lot of sense so they didn't do it.
These tracks are all family friendly:
