Like the person above, I too was surprised but in a good way! Cheryl herself would admit that vocally she is not the strongest of Girls Aloud (Nadine is imo). The press have been giving her a hard time this week so i assumed that she would have preferred the majority of the vocal to be pre-recorded so not to mess up. Good on her that she didn't. She did a great job...her dancing was great...her vocals were good (better than I've ever heard her) and it was just a good show! Good on you Cheryl!
