The composer and lyricist Hugh Martin passed away on Friday, at 96. Two of the standards for which he remains well-known are the wonderful "Have Yourself a Merry Little Christmas," and "The Trolley Song," both from the 1944 film Meet Me in St. Louis.
Here, from the film, is Judy Garland singing "The Trolley Song," with choral accompaniment:
