The song was written in the early 1930s, that is 30 years before he died, by a woman Party member whose name I cannot remember. Does anyone out there know?...

Cast your eyes up only an inch, Ada, & you will find your ? answered at end of previous [tho some years earlier] post. You seem to have missed this bit, so I copy it again here.

The song (in case you thought I had completely forgotten about it!) however has absolutely nothing to do with the events described, since they were written in 1935 by a woman communist (teacher I think) called Elin Williams. Thje last I heard she was still alive though into her 90s.

BTW, this song was part of my 1940s youth also!
