Further to my amends just above, I've just recalled part of another verse JT has recorded for this (possibly as a substitute for the last verse, though none of what Bru posted seemed new to me). Perhaps someone else might be able to fill in, if prompted? I can't dredge up any more than this from the old grey matter, regrettably. I know it was from towards the end of the song.
"Mrs Harris, just think of the middle classes, waiting to give generously to your cause?
With compassion their hearts are truly bursting to thrust a cheque into your grubby paws."
