Yeah, “Wonderful Christmas Time” is an awful song. I don’t agree on “Little Drummer Boy”, however. With the right singer I think it’s a good listen. I do wonder why anyone would think it’s a good idea to play a drum for a newborn infant. That seems like a bleeding idiotic thing to do.
I would like to add that Yoko Ono almost single handedly ruins “Happy Xmas (War is Over)” with her awful singing in the chorus. I listen to the Sarah McLachlan version so I don’t have to hear Yoko.
