"For way too long those within 'Cecil Sharply House' and beyond, have kept the songs locked away, "

They were locked away in some antiquarians notes or generally unheard beyond the garden wall of some cottager until they were placed somewhere they could be found. Where on earth do you think people like Martin Carthy, Seth Lakeman and many more go to find matieral once the source has died?

Have you looked at the publications made available in recent years or read about the educational projects giving these songs back to the descendants of the people they were notated from?
