You have just quoted the precise text in the DT (see my first link above, which I provided for a reason) apart from the final verse given there, about which I expressed doubts.  PP&M's copyright claims from that period (and those of many other similar revival performers) are very often, to say the least, misleading; they may perhaps have altered a few words, but they certainly did not write the song.  Your question has already been answered, I think.
