If this is the show I remember, I heard it briefly in, perhaps, the late 1960's and announced or narrarated by Jack Gwyn who had been in radio and television here.

There would then be a 30-second commercial spot and then the rest of the program ending with, "this has been Jack Gwyn with another custom of Christmas.
