As everyone was so kind with their recommendations I thought I'd come back to say that I had a great time at the show, it was really quite spectacular, a stadium full of flashing wrist bands was incredible to see.
My favourites were: Paradise, Violet Hill, God Put A Smile On Your Face, Fix You and Clocks. I would say they were on top-form but I've never seen Colplay before. Chris Martin was so appreciative and humble aswell.
Poeple were doing the oooohhh chants from Viva all the way to the tube station lol.
Definately a convert. Thanks all.
