He did. I have to an extent, in my version, folk-processed it [with Peter's knowledge & not disapproval] by reversing the order of "We would swim in the brook" and "We followed the reapers" verses; seems to me to make just a little more effect that way, going straight from the "hedgerows" to the "Things they do alter ... the hedges all fell".

One of his best songs ~~ indeed, I said in my obituary of Pete for The Guardian that it was IMO among the best songs of the Revival, and quoted the whole of the "Bring up my sons" verse. The obit can be found here
