Seems quite sensible for a relatively new South London club (who incidentally like everyone else are doing this because of a love of the music) to promote what will probably be their biggest night hencefar, incidentally highly recommendable if you are within travelling distance, nice atmosphere, and a few minutes walk from Deptford Station (itself only about ten mins from London Bridge), well worth supporting.
Well I'll be there anyway If I can get in on the night.
