Would you be entertained all the way through a Rebecca Ferguson concert?
 

Or would you get bored half way through?, serious question:).

If I were to see her I predict I would get bored half way through because I think it's important for singers to not just stand on the spot and sing but to show personality on stage and connect with the audience, make full use of the stage or use gimmicks (if required) to entertain people because this will help to get them singing and dancing so they've had a really good time, plus make them feel that they would want to come to your concert again and to get positive feedback:).

I wouldn't even make it half way!!!!!

I've managed to stay awake without losing the will to live throughout a Michael Bolton concert and a Donovan one... I think I'd manage Rebecca no bother!! :)

im going to be in the minority here i think, obviously rebecca has a very decent voice, anyone can see that but i have never actually been wowed or even entirely impressed by one of her performances.
