Thought I'd Google & see if I could find the whole documentary somewhere, and bingo: Watersons Travelling For A Living 1965 BBC

Also tried to find a link for the other one & found something here: Play for Today - Land of Green Ginger

Note: These may not work for everyone; Land of Green Ginger is an exe (type of Windows) file, so if you have a Mac you may not be able to access it --
unless you have a helpful friend with a PC. Travelling For A Living is in 3 parts and is a rar file, and may also be problematic if you have a Mac.
