I'm sure any alternative or rock club will be not only friendly towards Rocky Horror Show attendeeds, but will probably be expecting them to arrive in droves.
Well it's just a jump to the left................
I've loved and been to many a rocky show, would love to go with a group to one in London. Please add me to any list!
Not from London so no idea... Slimelight is meant to be good but I am sure that's members only. London must have some clubs I am sure...
