There must be somewhere a bit more central although I can't think of any 'off the top of my head'. Oh there's Norwell but the pub's a bit small.
The weekend of the 9th April is Banbury Song weekend - perhaps something could happen there - someone would need to contact Merek and Dary. However it would be good to organise a whole weekend for Theresa. I'm sure Ugthorpe Lodge near Whitby would love to host a weekend but it's a bit too far north presumably. Or perhaps Alcester's song Weekend venue would suit?
How about Preston, Angie and Ken's venue, not the school but the pub where's the 4 Fools is this year?
Any other ideas?
