Tobyjug, are you sure about Eric Winter writing 'The Man..'? My info is this:
From the pen of "Paddy Ryan" (Dr. R. E. W. Fisher) written in 1938 when he was a medical student. He recorded the song a year later, with The International, as the first release of the nascent Topic Records. (Jim Lawton, uk.music.folk, 24 Jan)
