On a slight tangent: I came across a 19th century parody of "Babylon Is Fallen" the other day. I haven't got a date for it yet, but my guess is that's it's roughly 1840-70s.
It's on a political theme, written after an parliamentary election in Bradford (Yorkshire, UK). The Tory candidate (who's name is Hardy) has failed to be elected, in favour of the liberal candidate. Instead of Babylon, it's "Hardy's fallen, to rise no more".
Does anyone know about when the original version was written or printed? (Bruce O said it was Henry Clay Work, the first version of the song in DT.) And does anyone know when the version with the line "...to rise no more" (which isn't in Clay Work's) was published?
