Sorry to put you out Wm, but Nick Dow is the driving force behind this and he is very familiar with the known Gypsy repertoire so I imagine if it related to other traveller material he would already have spotted it. All of the songs we are currently working on have come from Gypsies. I was already aware from studying collections like MacColl and Seeger, Mike Yates, Gwilym etc., that there was a strong tendency among Gypsies to hybridise songs and to piece together half-forgotten lines from songs. I know this can also be a feature among settled singers but it seems to be particularly prevalent among Travellers.
