It all happens in the bar - last Tuesday we also had people dining, and others playing dominoes while the music/singing was happening. Some people listen, some don't.Totally informal - no admission charge, no set order, you just do something if you feel like it and there's a gap. Usually I'll sing about twice in an evening, but I once went two consecutive months without singing, just joining in choruses. This month attendance was down due to holidays (especially instrumentalists), so I did five songs, and the other singers filled their boots too!
But Public Entertainment - nah, it's just a few folks amusing themselves.
