“May Day 1894” is a song based on a poem by William Morris in the style (I think) of the Byrds late 1960s:

From the album “Chants for Socialists” the singer/composer Darren Hayman says:
“In the socialist tradition we would very much like people to pay for this album within their means. You can pay nothing if you like, or whatever you feel the record is worth.”
