I notice that the questioner doesn't say where he is asking about.

Here in England I remember Christmas parties at Grandma's (in the 40s, 50s) where everyone did a 'turn'. "The touch of the master's hand", "Seated one day at the organ" Uncle Cliff's (imaginary) performing fleas etc. And My mother or one of her sisters would play for everyone to sing. Our dance club still does have summer and Christmas parties where people are encouraged to entertain.
