Judy Garland sings "Have Yourself A Merry Little Christmas"

From "Meet Me in St. Louis"
Here's a synopsis:
It's 1903 and the well-off Smith family, with four beautiful girls, including Esther (who's just fallen in love with the boy next door) and little Tootie, learn that their father has been transfered to a new job in New York, which means they will have to leave St. Louis, the upcoming World's Fair and all their friends and family, behind, setting the stage for this poignant song.
