I have no doubt what you are saying is true Peter, but in my experience I have met far mor singers who appreciate music than I have musiians who appreciate singing - though I wouldn't want to generalise on that.
Two stories on the hazards of public performance:
Blind Henry Blake of Kilbaha, South Clare, was the last of the big Irish Language storytellers here.
Henry lived on the Shannon Estuary and related an evocative account of the time the sailing ships travelled up and down the Shannon, when he heard the shanties drifting across the water on summer nights.
Our friend from the previous story sought him out to record - he agreed, and they adjourned to the local bar, which was empty of customers.
Halfway through one of Henry's big tales, a man came in, turned the television on and sat down to watch a football match.
Henry stood up and walked out - he never told another story.

Back in the seventies we recorded a storyteller from North Clare, Pat MacNamara of Kilshanny - Pat had a large repertoire of tales ranging from about five minutes up to over an hour in length - he also had about eighty songs.
The landlady of the local pub was kindness itself, she was around eighty, like Pat, and they had been lifelong frends.
She took the bell off the door (it was a combined shop and pub) and allowed us to record all Pats songs over a few afternoons, but when it came to his stories, she refused flatly.
She explained that in earlier years locals would gather to hear Pat tell stories, but she put a stop to it when he began to start his longest stories a short time before closing time - after this had happened half-a-dozen times she vowed she would never allow another story to be told in the bar.
