Liner notes for Songs of the Spanish Civil War Volume One

The above link reproduces the complete liner notes to the Songs of the Spanish War which may clear up some of the confusions about some of the songs discussed above. It includes the version of Viva La Quince Brigada sung by Pete Seeger but does not attribute authorship. I now believe that this version of the Ay Carmela was written by Bart Van Der Schelling and I some time ago started another thread specifically about him and the evidence that he wrote the song.

Bart Van Der Schelling Any Information ? thread
