I suppose that my wife,Liz Jenkinson,should be included on the list having played a Maccann for thirty years.
She currently plays a 67 keyed Wheatstone Aeola from the early 20s.
Does anyone remember a concertina player from Nottingham in the early 70s called Gren?
I'm sure he played a Maccann at the old Nottingham Traditional Music Club (NTMC).
