I saw...Dizzee Rascal, Muse, Spank Rock, Sway, Hundred Reasons, The Streets, Feeder, Lethal Bizzle, ****disco, Panic! At The Disco, Arctic Monkeys, The Automatic, 2 Many DJs, Placebo, Soulwax...possibly a couple others I forgot.
The best for me were Hundred Reasons, Lethal Bizzle, The Streets, Dizzee Rascal and Feeder.
Annoyed I missed C&C for the bloody Arctic Monkeys, who I found to be jaw-droppingly dull.
