Mr Red's list has a few entries, mainly some of the rather peripatetic music sessions around Exeter, which have died or moved on. For a more up to date list try Flaxey Green , either their diary dates or the lists of sessions and clubs.
I'll probably be at Copplestone (5 miles from Crediton - last Tuesday of March); in Sticklepath for the singaround on Easter Sunday (20 miles but worth the trip if only for the pub – but wrap up well it's freezing there!) and in Sandford (2 miles) the following Tuesday. The second Sunday singaround in Bow (8 miles) won't be happening in April as they'll be in Topsham putting on their "Great War Presentation ".
