I think buying the Cherry Red Compilation is the best bet. Playing it loud in your own basement/bedroom whilst reading old copies of The Sunshine Playroom Fanzine. Anorak optional.
Doors 6.30
Finish late.
Over ten acts.
Oh if only I had seen that too. Got a wedding that day so can't even go last minute. As an aside -Popguns are playing in Brighton sometime soon but not sure exact date.
