My girlfriend from high school had an elder dad who thought Rocky was too violent, so she spent the night at my house so we could sneak to the movies LOL
Basically the JWs would say something about pretty much any singer because all of them were WORLDLY. Beatles did drugs, Elton John was gay, many were said to have Satanic influences.
My JW sister, after seeing a bunch of Buffy the Vampire Slayer videos in my daughters' room and a few very innocent Rock band posters, decided that it could be contributing to whatever issues I had going on at the time with my kids. LOL I just tried to stifle a laugh and later laughed about it with my oldest daughter who was 18 at the time.
