Not that it makes any difference in how it sounds, but I think the punctuation of the end of that next to last verse should probably go:

    Divvunt say "Ye geet fond thing"
    nor "Sing, ye flat arsed bugger, sing!"

Forsh mentioned it in the post a few years back (01 Aug '03), but then it was never picked up, even in the 'corrected' version in the same post.
