Chirsty learned the song from Hamish Imlach, who recorded it on his first Xtra album (mid 60s, same album as "cod liver oil & the orange juice"), and I understand, that was Hamish's reworking of the J.J.

Hamish carried on performing it regularly right up to his death. (I sang it at the post funeral tribute).
