They were still in China and the ceremonies was broadcast to the (prude) US. So if they didn't want to have *beep* interrupting their song ;)

AFAIK, the singer is actually an opera singer.

>Well I'm not so sure that London and Jimmy got to "rock you" the way they would have liked to. Apparently the lyrics to Whole Lotta Love was changed to "...every bit of my love". I don't think that I've ever heard that song sung so badly either. What was that, opera?
