The Beatles were into child molestation lyrics:
I saw her Standing There has the lyric Well, she was just seventeen, you know what I mean
.
Going back further to the 50's rock stars you have major rock stars like Elvis and Jerry Lee Lewis who were actually doing underage girls. Or Jimmy Page of Led Zeppelin who at age 28 took his 14 year old girlfriend on tour with him.
Its kind of weird how many of our music stars were in to underage kids and how society largely just shrugs.
