Most of the comments on here are complete rubbish.

I watcehd a youtube clip of heidi and the "original sugababes" performing hole in the head on top of the pop and it was god awful. see it for yourselves - http://www.youtube.com/watch?v=8_aO-iNUT88

the girls are singin over their own vocals and keisha and mutya look so out of place its ridiculous, keisha has an amazing voice but none of you can deny that in the get sexy video keisha is the one that looks out of place when they are all dancing together.

the performance was good, not show stopping, but not crap either. at least the sugababes aren't miming and are showing that they've got guts.
