I learnt this tune decades ago and always assumed it was Irish, but now with the aid of internet discover it was a Scottish pipe tune originally. Well this is how I've played it for ceilidhs. No harm done.
The accordion is a rather nice Fantini 72 bass but more or less same size as 48 bass as it has slightly narrow keys. had rather generous amounts of grease in the bass mechanics which ironically caused sticking, so had to dismantle and clean.
