Since I learnt the system (North Yorkshire version) from my Grandad long before I knew Jake, who taught with my Dad, I can definately say that he was NOT the originator of the system.

Molly Metcalf as such didn't exist in real life. Jake wanted a lead into his song and having spent a lot of time up in the Dales realised what hard going it was. A true teller of tales he made Molly up from his knowledge of such things.
