Well at least you didn't come home from NESI with your wife telling you since you have two working concertinas, she can use your twenty button. Never mind she has 7 guitars and 4 mandolins.
Mine has a lovely singing voice, but doesn't play an instrument , or have any desire to. But she bought me my Rochelle, and offered to pay for the Morse I just ordered. Seems to run counter to the behavior displayed by some other "concertina widows", as reported by other members of the forum.
