---Having had Chinese friends beaten up whilst being taunted with chants of Oh Mr Wu then forgive me for taking it a little more seriously.---

Bollocks, Sean. Complete confusion of post hoc & propter hoc. They'd have been beaten up anyhow for being Chinese & hence other; not to mention for being THERE; not because the yobbos happened to know a song called Mr Wu. If they hadn't had this song to fall back on, they'd have found another chant. Or do you think they'd have said, "Oh, I say, chaps; we can't beat this Chin{ese fellow} up because we haven't an appropriate song to do it to, dontchaknow?" I have had Jewish friends beaten up, but their attackers didn't sing Cohen The Crooner as they did it...

It isn't even a stereotype: the humour of the song derives from a man in love being careless, not from his being Chinese.
