Well we could go back to the sixties and beyond to single out songs with dodgy lyrics ("of their time"?) The Beatles had some, the Stones had some, Elvis had some, Ol' Blue Eyes had some, Abba had one that I can think of. We can ban 'em, restrict 'em, moan about 'em. Or we can decide that most of 'em probably won't deprave or corrupt, accepting that humans are fairly resilient on the whole, and bite our lips. It's complicated and I'm not going to tell you what I think!
