With this in mind a fellow Turnip has suggested it would be a good idea to set up a Topic specifically for this search.
I have discussed with the head honcho and, even though the likes of Sir Cliff etc are concerned that the music 'wot they rote' should be protected etc etc, we agreed that it would be OK for such a Topic to appear here therefore I am pinning this new Topic accordingly. I will also do something similar in the Television & Film sections in due course.
I will start the ball rolling by repeating my request of a couple of days ago.
Looking for the 1933 recording by The Vagabonds of 'When It's Lamp-lighting Time In The Valley'.
