Somehow I have my doubts if these kiddie songs really rock that much...
If only you could select which songs to teach 'em... would sure be a funny thing to see a primary school class sing "Highway to Hell", hehe...
Btw, a friend of mine works in a Kindergarten, and he's a metalhead. He's tattooed (a huge dragon wielding a scythe, all over his back, and an inverted cross (!) on his right shoulder), he usually runs around in metal T-shirts, and he even taught children the classical Heavy Metal hand gesture... I think you know what I mean.
When his colleagues ask him why "his" children make that gesture, he says that he has taught them to make "the snail"...
Stefan will probably teach children how to play CS just right... or wait a minute, nowadays it could be that a six-year-old will own him on any map - the times, they are a-changin'... 9_9
