I've just seen Dave Hunt's entry, re- 'Where Shall We Be In a Hundred Years from Now?'
I recall this song from days at The Old Crown FC in Birmingham in the 1970s. I think the singer was Stewart Jones who certainly had the loudest voice I've ever heard. I sang it too with what words I could remember from him, adding a few verses I found from a book (can't remember which one).

No idea about the tune, but the chorus certainly had elements reminiscent of the 'Death March from Saul' (if that's the one usually played at state funerals and the like).
