Strange my last posting has disappeared.
To repeat myself, Scan Tester used to play a Bandonion and the story goes that he only took it out to sell it.He sold it many times and when the new owner could not get on with it ,he purchased it back again, but at a lower price than he sold it for.He did this many times and thought it was a good source of income.
There was a poll on Bandonion and Chemnitzers and it was unanimously agreed that they were not Concertinas.I did not vote so please do not blame me.
If the original posting turns up,please ignore one of them.
