Hi, Rusty!
Yes, I knew it was recorded by the Trapp family singers, but had to look up the composer's name.....Katherine Kennicott Davis.
I think your idea of what transpired at the end of the recording tallies with mine......but I don't understand the concept?
Unless I missed something, Wikipedia does not appear to be any help.
I don't think I much like the Bing and Bowie version.
You didn't say what you thought of it?
I remember coming across it when trying to find some Bing to play at my father's funeral, fifteen years ago.
As you know, he was a huge Bing fan...... and I grew up listening to Bing!
We played "O Holy Night" and "Did you hear what I hear" for the processions into and out of the chapel!
Both were suitable, as the funeral was between Christmas and New Year.
I don't remember the Boney M version of "The Little Drummer Boy"....I shall look it up later....
Now I am going to wash my hair!
