There is some contrary evidence too......

"Please tell me what the Bothys were, if they were not places where Scottish farm workers slept, lived, told stories made their own entertainment and sang their traditional songs[They did it because that was how they made their entertainment]
Willie Scott sang at hunt functions[a social gathering],at many hunt functions,traditional songs were sung,they were sung for entertainment."

Absolutely correct Dick but let's remember these were private functions and hunt suppers whilst held in pubs would be in a separate room.

These were inclusive social gatherings - not everyone was invited.
