Les, one of the 'treats' for me of the Polkaworks workshop was being able to 'keep an ear open' for what six experienced musicians playing in a tight band, without amplification in a smallish room were doing.

They were playing the same 'version' of the tune, but, as they made a point of demonstrating they, were often not playing the same notes, and not the same each time through (which they said was useful to dancers). Unless someone wrote out a six 'voice' score only the ears - aided in that case by an explanation - are going to deliver that to the brain.
