I first heard it as sung by M W-R around 1972 but subsequently visited CSH where the librarian dug out a book with zillions of verses and kindly photocopied some for me(was copying them long hand) I like John Tams adaptation of the words but don't sing them, I sing th ones from the book. Another book worth re-visiting or discovering is Lewis Winstocks "Songs and Music of the Redcoats" which I believe has the M W-R version in it, if you can see your way through the tub thumping bits there are some great songs in it that I do but haven't heard anyone else doing. There is an LP of the same name, which I have, that has a few on with M W-R, the Yetis, Kieth Kendtick, Bob Fox et al .
