Yes but "Professional" artists are prepared to accept what might be seen as less than the "rate" in order to keep themselves in the (folk) public eye out of the Festival season and between "concerts".

Seems to me that this is also a "professional" attitude. (They came to see me at the club so they may come to my concert/festival booking if I make a good showing here tonight?). Isn't it, somewhat extended perhaps, a form of showcasing.

In "business terms aren't we talking Market Share, Loss Leaders and such buzz phrases?
