Apparently after a friend of Peggy Seeger took issue with him he later changed 'but I am a free man on Sunday' to 'but I have my freedom on Sunday'. That also gives the opportunity for the final chorus to be sung : 'but I have my freedom -and YOU have your freedom and WE have our freedom on Sunday'.
Almagal LOL! I've never heard this sung "..a white slave...": always "...a wage slave...". And LondonLouis - while this was indeed written to commemorate the 1932 Kinder Scout mass trespass it certainly remained very much live throughout the 60s and 70s when I was a rambler from Manchester, and is no doubt still sung today on walks throughout the region. And 'Saturday Night and Sunday Morning' was written in the mid 1950s about east midlands city Nottingham by Alan Sillitoe while convalescing in Mallorca: it's associated with the 1960s only because the 1960 film was popular then.
Untrue Louis on this occasion. Here in Lancashire it's common practice to go for a ramble over the moors. I'm a 21 year old lad and me and mi' mates can enjoy newt better than a good ramble over the moors, a campfire and a coupla' spliffs. You southerners don't have our landscape and therefore have no option but your hard-drinkin' and what not... Wonderful song anyhow... Was it the themetune to Fred Dibner's TV program?
A less uplifting take on the attractions of the weekend can be found in songs like "Blue Monday". This song reflects the uplifting radical ideology of the 1930s. By the 1960s, we were into the "Saturday Night and Sunday Morning" era of the hard-drinking, hard-living weekend. To be fair to MacColl, the issue of city dwellers getting access to green space was a very real one during that 1930s period.
I assume this would have been written in the 1930s, when radical ramblers from Manchester (led by, was it, Benny Rothman?) challenged the right of landowners to close off the Peak District to walkers. I've forgotten the full history, but they were successful enough to get the law changed in favour of ramblers.
