As mentioned above, the Mexborough concertina band's sheet music was bought by Nigel pickles, who released an LP with him playing several concertinas multitracked. He also did at least one tour playing numbers from the Mexborough Concertina Quartet. I believe Tim Laycock was one of the four players. I saw them perform at the Knaresborough Folk Club.
The Mexborough Concertina Club no longer has the instruments, and is a non-political social club. A number of years back, one of the bar staff decided to do some small scale brewing on the premises. Originaly the beer was only sold in the club, but after a while they had sufficient production capacity to sell it to real ale pubs and beer festivals. They brew some excellent beers. I particularly ike their Old Dark Attic. BLICKY.
Quack!
