Your version appears to be very similar to that recorded by Ewan MacColl on his LP, 'The Manchester Angel' (Topic 12T147, 1966) - which, incidentally, is my favourite Folk record of all time! And 'Sheepcrook and Black Dog' is my favourite track - it doesn't really get any better than that (in my opinion, that is).

It's also available on a later CD - 'The Real MacColl' (Topic TSCD 463,1993).

MacColl's version was based on that that he and Peggy Seeger recorded from the Dorset Gypsy woman, Caroline Hughes, in the early 1960s.

And it's not 'budgie' but 'budget'! This was probably some sort of bag which held the shepherd's lunch.
