Thanks, all.

Helen, I've never heard it on an album: I heard Peggy sing it live around 1970 at Shrewsbury Folk Club, where she and Ewan were often booked.

I'm pretty sure she didn't sing 40 verses, but given how firmly the tune is stuck in my head, perhaps she did!

It must have been one of the themes of the evening, as I'm pretty sure they sang the Ballad of the Trades on that occasion, too.

Steve, thanks for the book reference. 9 stanzas sounds nearer my recollection, such as it is...
