No not a Christmas movie or song but it's one of my favorites.   I got to go see it for my birthday when it first came out (aging myself but didn't say which birthday).   I'm the only girl and youngest of 6 kids, it was just Mama, Daddy and me.   We rarely even got to go to regular movies, just all 8 of us piled in the car and went to drive ins, so getting to go just the three of us was a real treat.  We even went out to eat afterwards.  I loved it so much I got my hair cut just like Julie Andrews after I saw it.   I do own the DVD and do watch it a lot.   I have a record made by the real family and my son gave me a SOM album last year for my birthday.  I don't own a record player any more but love album covers.
