My wife plays viola de gamba and I could very easily see a consort of viols and sackbutts getting together in a pub for a "playin !! " A night of Gibons or Tallis " Yes this sort of thing really works to bring new people into the fold and enlarge everyones lives . (As a night of Anglo and English concertina at the Albert Hall could broaden another audience )Ahh what fun !
