Substantially the same lyric, with some additional verses, is in the DT: JOHNNY BUCCA. Whoever posted it, though, chose an unusual spelling for the title, and jumped from that to the bizarre assumption that "This song may have come from the old days when the 'bucca' were the little folk 'piskies'as we now call them"... (!)

Spelled like that, it's hardly surprising that people have trouble finding it; though you should never rely on a search of the DT alone, as there is far more material in the Forum now. Neither can a search by title be relied upon, for obvious reasons. Searching for old johnny, on the other hand, would find you quite a lot of relevant stuff.

I have an idea that it was Mike Harding who started calling the song Old Johnny Bugger, and of course it caught on. There is a set in Harding's Folk Songs of Lancashire, but he doesn't say where he got it. This may have been dealt with in one or more of the earlier discussions. I expect that a list of links will appear at the top of this page before long.
