I have a VCR copy of The Singer and the Song - interviews with Sam and Harry Cox (though they never met)
Hope to make them available as soon as I can sort out the digitisation
Not sure of your reference to left wing, politically correct snowflakes C
The right wing establishment sacked both Philip and Charles (both left wingers) and eventually dismantled the 'Features Department' which produced all those wonderful programmes.
Charles's and Ewan's refusal to allow the horrific suggestion that all gypsies who wouldn't conform should be "exterminated", in The Travelling People' Radio Ballad proved the last straw.
There's an excellent account of the history of the features department in D G Bridson's 'Prospero and Ariel' "the rise and fall of radio - a personal recollection (still available, last time I looked)
It includes a description of the first appearance of Ewan singing in the street for a Manchester cinema queue in the 1930s - well worth searching out.
