Regarding that first tune... I'm sure there was a big old thread on here trying to get to the bottom of who the vocalist was. I'm pretty sure Horace said it was not him and it turned out that it was Horace Ferguson... If that was the same tune. and my memory is still working.
It sounds like there is a crowd who are seeking more music satisfaction, which I think you get more of when 1 or 2 sounds play... I do agree, the three sounds thing has it's own pattern, I've enjoyed plenty, but it doesn't give sounds much of a challenge, when as little as 14 tunes might be played by each, all night.
