Well Al, Jimmy played Scottish Country Dance Music to a strict tempo.
Before the sixties folk revival, the Country Dance scene was very strong in Scotland, but it was still fairly formal even in my time.
The real oldtimers told me of a very strict dress code, white gloves, patent leather shoes for the gents, no drink and a very strict code of behaviour in the dance itself and choice of partners.
Gentlemen were expected to dance with as many of the available ladies as possible and the ladies were not allowed to refuse an invitation to dance......some dances were called as "Ladies choices" and the roles were reversed.
