Partners/children/friends welcome. There will be some drinks but mostly Weird Shit From The Back Of The Cupboard so if you want to guarantee that a sane drink will be available you're probably best bringing it yourself. There will be nibbles and (if I have time to bake it) cake, and in case of Munchies Emergencies the Co-op is about 30 seconds' walk from our house and stays open until 11pm.
There may be Singstar if enough people want to and enough other people don't mind.
Any other questions that I've failed to pre-empt, ask!
