The researcher for this programme actually came to Mudcat in May 2012 to pick our collective brains, posting as 'mrsfifties' on this thread. I had some correspondence with her after that, and pointed her to Cecil Sharp's notation of the Hutton song on Full English and the article in English Dance & Song, amongst other things.

I haven't seen the programme yet, so can't say how sensitively the stuff's been used but, with all the doom and gloom around Mudcat, it's nice to know we can still be of service to the UK's national broadcaster!
