I posted a link on another Mudcat thread telling people interested in SCW songs, about a page of listings on Abe Books UK for a facsimile edition of Canciones de las Brigadas Internacionales. It now occurs to me that there might be many readers of this thread who would be interested and so here is the link
< a href="http://www.abebooks.co.uk/servlet/SearchResults?isbn=9788484723431&sts=t&tn=Canciones+de+las+Brigadas+Internacionales%2C%22">Book on Abe Books
It is the book compiled by Ernst Busch during the war for the benefit of the International Brigades volunteers. It has songs in a number of languages.
