Last year it was a case that all the music was pre-recorded and the acts were singling live - some of them were surprisingly good!
Great fun overall! I haven't bought a ticket this year but there are still some available, so I might decide it at the last minute.
Yes bands perform,Alphaville from the 80s for example playing this year.. loads of 80s/90s acts play,atmosphere is amazing,ragin I cant go but on a training week for work
