I agree with Mr Red, try eCeilidh. Double check on PELs then check again. If the venue usually hires for private functions they may say that they are licensed menaing liquor and music & dance. More than one promoter has been caught out like that.

The other thing is that events don't sell themselves, be prepared to work your arse off and want nothing better than to crash out in a darkened room when the music starts on the night.
