Cheers lads - knew you'd be good for some solid advice. Will get listening to some of those I don't recognise, to help make decisions on the day.
You'll perhaps not be surprised to know I had a fair few of those on my list - I'm very excited about seeing The Big Moon and Gabriels from your list J. From your's Matt I'm fairly sure Hot Chip clashes with Elton, which is a shame. But Say She She are belting, will be giving them a go!
Along those lines I am really hoping Joseph show up on the full list when that comes out next(ish) week - they are absolutely brilliant!
