LAVAL (France, Mid-'70s...)
In a previous life I was a dep drummer, here in France. With a guitarist buddy, we went to 'audition' for a bloke, apparently quite well off, who had invested heavily in his daughter to form a variety band. She was to play accordion and organ, the fellow had a tambourine, all that was left was to complete with the other musicians. The downside..? She (the daughter...) was about 14, and had, not only no musical ability whatever, but no interest in humouring her Dad with his fantasy.
I don't know how, but he had already got a gig for a village fête. My guitar chum desisted, saying (rightly...) that he couldn't follow what the girl was doing. I accepted, basically as money was tight at the time, and I shuddered to think of the poor spectators if she did the 'show' alone. The evening came and went. We weren't asked back, but I got paid. The ruse was simple: I ignored whatever she was doing, and maintained a reasonably danceable 'disco' beat the whole evening. Everyone danced. No-one could have guessed the titles of any of the numbers she 'played'; the variation came from me switching to 3/4 or 6/8 occasionally. I don't think 'Catherine et son ensemble' played any more gigs. All part of the job, really.
