Some tunes are linked unbreakably with their dances.
Dorset 4-hand (parts 1 & 2 which is a pig to play because it's in A , has twice as many notes and needs to be played faster)
Oswestry Square (well, it's Welsh but we're on the border)
Chinese Breakdown (we always did an American square at Manley)
Black Nag is a Playford dance - Rhodri Davies calls it Mr Playford's best ceilidh dance.
