According to Alan ....... the concertina was taken into the Hobgoblin Shop in Birmingham and offered for sale.
Hobgoblin staff recognised it as stolen as they had been advised of the registration number.
The police were called and the person trying to sell it was arrested.
The police rang Alan, who was at Saltburn Folk Festival, to say it had been recovered.
Alan is dying to get his hands on it again He said he was amazed and very grateful that so many people had been so concerned and so helpful.
