No - I can't come out to play this weekend - got to tidy my bedroom

Got that info for you - the vullage hall costs £ 150 for a Saturday night and £ 90 for a Friday night (both 6pm to 12pm)- deposit is £ 100
You have to organise a pub to come in and run the bar - they normally do this for free if they are charging pub prices - maybe £ 10 for a license - the hall takes 180 people
Hall is currently booked until June - so say 3 months booking/lead time required - other rooms aren't a lot of cop

An alternative is the British Legion at Harpenden where I am a member
They have a similar room for £ 95 a night
It's separate from the Legion, but the bar runs through into it - so no palaver in sorting that out
Harpenden may be better located for the audience you are seeking

Hope that's okay
