The Comedy Pub is a great venue for gigs, my band and I have previously played there and I like the atmosphere a lot. It's also relatively cheap if you want to ask friends to come support you, entrance is £6 or £5 if attendees can name what band they are coming to support on the door or ideally bring a flyer of some kind.
This Friday 27th June, there is an event hosted by Dead or Alive, and bands playing are:
THE FOLLYLUZ AND LA EXPLOSION SUDACA
BUFFALO FISH (great name)
