What's entertaining is a personal view and a private session in a house or similar is one thing.
Playing music purely for your own entertainment in a public space like a public bar, whether invited or not, without considering the 'regulars' negates the whole point of the music of the people.

It does happen and it shouldn't- we're not missionaries.
DTG i think we mostly agree, but I never said that piper was rubbish'. Dick did, but I have never heard him and as per your original post, neither of us has given his name.
Personally, I can get too much of music, and long spells of inactivity bring me back with a fresh burst of enthusiasm. This is a longer spell than I've ever had & expect the same will happen when/if things ever return to normal
