This has been bothering me for awhile. I believe it is from the 90's, I saw it on Canadian TV. It might be a religious movie but I doubt that. It is a christmas cartoon special and or movie about a tiny angel( who perhaps comes to life from atop the Christmas tree) and takes place mainly inside a house. He does something to save christmas. I remember a song the angel was singing. Gloria in excelsis deo. It's not the popular song but it seems to be somewhat of a remix. Thanks for your help.
