There are very few places in the UK where source singers still exist. As Nick can attest, and Gwilym and Sam Lee and others, there are pockets of Travellers who are keeping these old songs we treasure alive, and indeed a whole interesting culture related to music. I've seen plenty of threads here that are blatantly nothing to do with folk so I know where my preferences lie. I fully support the work of Mike, Nick, Gwilym and others who are working hard to document this music.
