I wrote the words to this song circa 1976. Gary Aspey ( whom I knew) wanted to buy it from me. I refused, but gave permission for him to record it. My copyright is registered through Robert Kingston Music and I have received royalties via PRS.

There is no way someone could have been singing it in the 50's. Other folkers, including me (Clint Ackroyd & The Rat Trappers) from the same era and area - eg Roger Westbrook - also perfomed it and can confirm.

You will not find any recording of this prior to Gary & Vera's. The verses posted by Mmario in 04 are not mine - clearly it's been modified/localised later.

Yes, the tune is "The Keeper".
