Question Author
This is the last question that I need an answer for. I was hoping you had it when I received an email saying an answer had been found. I think the scope of the clue might be widened to include any popular song that was released around Christmas time, maybe as far back as the first world war.
In the meantime, I am awaiting a reply from my daughter who has the original sheet with song titles in initial form and a precise description of the clues.
Thanks for trying wideboy, I too have looked at the sites you mentioned and several more besides.
