Hand's up all those that have never heard "John Brown's Body"! It must be one of those songs that is known to the whole English-speaking world and even to those just starting to learn English. I certainly have known it since childhood, but the version I sing is that performed by Wilfried Drygala. I don't know where he learned it.
I well remember joining in a pub jazz session whilst on holiday in Richmond, London sometime in the mid-1990's and surprising the people around me with Wilfried's version which has six verses compared with the four-verse somewhat complicated version provided in The Story of the Jubilee Singers
and I loved wailing the "Glory, glory hallelujah!
chorus in the quite normal manner, to us that was, of the typical demented English pub crowd, much to Wilfried's chagrin and annoyance.
