This really annoys me, sing what you want, you are not going to give your child am intro to the history of the song before you sing it, its like saying should i read my child a fairy tale as the are really adult tales..
I've been wondering this actually. I loved Rolf Harris songs when I was young. I saw him live in Bristol last year and he was amazing and entertaining. I'm personally a bit gutted. But then I would never play a Gary Glitter song.
