The possibility of getting a recording which is suitable for general release in the conditions we are discussing is negligible.
I can recall only one occasion in thirty years where anybody was ripped off in the described circumstances.
The main concerts at one of the early Willie Clancy Schools was held at Spanish Point Convent rather than the usual venue, which was being worked on.
Just before it began, the owner of a well-known record company appeared, swept aside the pre-arranged p.a. microphones on the stage, proceeded to place his own in a suitable position for recording and sat down in the front row.
Because of who he was, the organisers did not stop him, and he made ready to record the concert, until the fiddle player Sean Maguire appeared on stage, walked over to your man and said, "My name is Sean Maguire, my agent's name is **** ****, my recording fee is *****, and if I see your fingers anywhere near those buttons I'll feckin' dance on them".
Such behaviour is extremely rare, should not, nor would be tolerated.
