We particularly loved the security guy bouncing along with his little girl.

Eleven and 14 is very young to be in an established band, but Keisha Sugababe started at 14 and isn't doing too badly, interchangeable band mates aside. While you might expect people that age to be singing into their hairbrushes and doing their Grade 4 piano exams, the precocious American sisters have toured, won famous fans, and, on the basis of what they're doing tonight, recorded a good album. It's definitely not pop either, not twee enough. Oh God, it's growing on us. Who is this Brad they're singing about? He sounds like a nutter.
