Mine's got to be either Calvin Harris or Mark Ronson.

Calvin Harris really worked the crowd, as did Mika.

So, let me know who was your fave

Mark Ronson was just brilliant don't you think?

And Calvin Harris made us so happy when he actuallky utilised the whole stage,I enjoyed him so much I bought a ticket to see him in concert=]

Yea Calvin Harris was such a good performer Mika was great aswell... I think Natasha Bedingfield could have been a little better as good as she was... all of them were great overall even the ones that i didnt really like.... BUt OMG, it was all gooooood

I thought Calvin Harris was brilliant as he did get involved with the crowd. McFly were good too, albeit a bit short though. I was NOT impressed with The Pigeon Detectives as they seemed a bit arrogant, they werent the only ones who had to cut their set short!!!! Still had a great time, even though I have a sunburnt face! I've learnt my lesson!!!!

I thought the pigeon detectives were amazing! - But i seem to be the only one! I was stood in the crowd singing on my own never mind!
I have to say though the best acts were The Maccabees, Mark Ronson and The Hoosiers (all on the 4music stage).
So next year im just going straight to the 4music stage!!

Girls Aloud. Looked VERY nice!
