Here is a link to a song about the Spanish Civil War sung and performed on the Anglo concertina by Angela Tuckett It is placed in the Roy Palmer collection of the British Sound Library HERE where it is called "Many years have passed" although I think it is correctly called "Return To Spain". I had some correspondence with Roy Palmer back in 2010 and he said he thought the performer was Angela Tuckett and that the words to the song were written by ex-IB volunteer Bill Feeley. I notice that some of the words sung by Angela on this rcording are slightly different from those printed in a pamphlet given to me by Roy and published by Oldham Lesure Services, 1986, called "Songs of the Spanish Civil War: The Oldham Men who fought in Spain" and I wonder if Angela Tuckett contributed something to the words she sings?
