How about “Guardian Angels” by Harpo Marx – seems to me it was on a Christmas Album by Mario Lanza many many years ago – I think the melody is interesting instrumentally and also has some nice chord progressions – I’ve been meaning for years to try my hand at making an arrangement that would somehow combine “il est ney” and Salzedo’s fast runs from “la Joyeuse” – also, if you have some strings available for your project, I am always fond of Grandjany’s “Aria in a Classic Style” for any season of the year –
