"I will never condone something which puts fellow musicians out of work."

Singarounds & Sessions? (do hope me singing a couple of folk songs last time we met in the upstairs function room, didn't put any professional performers out of a job!)

Singarounds & Sessions are amateurs getting up and doing it for themselves. Karaoke may indeed be cheesy and formulaic, but ordinary non-musicians who wouldn't otherwise 'have a go', do it for a bit of fun and camaraderie, and that's all.

I think that's the "spirit" of folk music anyway, even if the creative options and results are more limited.
