I like this version too.
I am not sure you have to worry about alluding to a Christmas Carol.
Mozart ripped off Beethoven. With impunity. Without a second thought. Beethoven ripped off folk songs.
You're a world famous composer and you rip off your ancestors. It's what you do.
You have low priced auto insurance and your call yourself Geico. It's what you do.
Hi David,
Thank you very much for your kind comment. I am really glad you like this version as well. I am also encouraged so much by it.
You might think I am too nervous, but I do not want my song to be something the listeners are concerned about its resemblance to other songs. Even though they do not doubt its originality, their attention might be distracted from the song itself.
