Years ago my 4 year old and 9 year old daughters knew exactly who Weird Al was from his parodying the Star Wars song (sorry I can't remember the name.) from Radio Disney and other songs that came on that channel. Hilarious!! Long before that I had a girlfriend who was totally in love with Michael Jackson's music. It pretty much made me wanna vomit, but I was dating her so I had to put up with it. Then he parodied "Beat It" and I thought it was the funniest parody I ever heard of a song.
Oh hey, can we add ZZ Top to that list of over 30? Actually 40 years. Billy, Dusty, and Frank have been together since 1969. (Before that it was Billy Ethridge and Dan Mitchell or Lanier Griggs and Billy Gibbons, but that was only around the Houston, Texas area and before 1969. Their first album only has Billy, Dusty, and Frank.)
