I have had the same problem myself so many times going out clubbing in London , Birmingha, etc and I never know where to go clubbing that is playing the type of music such as disco that I'm into. Then I was recently told by a friend of mine who goes clubbing about a service called clubhunt which gives you full club night listings for all club nights in all towns/cities in the U.K sent direct to your mobile phone. You can search for clubs playing disco music, find out what time it is to get in, entry fee etc. All the info is on their site
http://www.clubhunt.co.uk . I hope this helps out some frustrated clubbers who want to go to disco nights.
