I'll try a blue clicky for that other thread: Ulster Scots Music.

The Ballad of William Bloat was written by Raymond Calvert (1906-1959). Calvert was born at Helen's Bay, County Down (about five miles from where I am right now), and educated at Queen's University, Belfast. He wrote the ballad as a recitation for some bash at Queen's.

As I said in the other thread, any version that has "Dublin" instead of "German" in the penultimate line has got it wrong. In the last line, "Belfast" rather than "Irish" is also wrong. Our own Digital Tradition is wrong on this latter count: I think this mistake probably got its enormously wide currency when the poem was rendered into a song - by, I believe, David Hammond. The Oxford University Press is wrong on both counts, and for good measure has the poem as anonymous.

I am away from home at present and have been able to put my hands on only one correct version. This was in Rich and Rare, a magnificent anthology - surely the best - of Irish songs. poems, recitations, all authoritatively edited by Sean McMahon. He thanked Irene Calvert for permission to reproduce William Bloat. I have a feeling the ballad was first published by Blackstaff Press.
