I read somewhere that the line up/new bands play until 4ish and then the bigger acts start. Is this true??

no particularly wen i went the newish acts started first but then they were all mixed up 2gether. x

I don't think this happens.. for the past 2 years i've been all the bands have been mixed up throughout the day, last year Mcfly were first on and I wouldn't call them a new band.. lol..

The headliner is the band/singer who will go at the end, they don't have to be amazingly popular, but last year it was Kaiser cheifs and the year before I think it was Shane ward? I dont know.. i cant remember that far back.. lol.. but basically they all mix together and then the headliner at the end will play for about half an hour x

How long does each band or performer go on for???

All the acts have between 1 and 4 songs, and then obviously the headliners get longer.
