Have yourself a merry little Christmas

"Have Yourself a Merry Little Christmas" is a song introduced by Judy Garland in the 1944 MGM musical Meet Me in St. Louis. Frank Sinatra later recorded a version with modified lyrics, which has become more common than the original. The song was credited to Hugh Martin and Ralph Blane, although during a December 21, 2006 NPR interview, Martin said that Blane had encouraged him to write the song but had not had anything more to do with writing it. In 2007, ASCAP ranked "Have Yourself a Merry Little Christmas" the third most performed Christmas song written by ASCAP members of the past five years.

The song was written while Martin was vacationing in a house in Birmingham, Alabama, that his father Hugh Martin designed for his mother as a honeymoon cottage. The house was located in the Southside section of the city, across the street from Hugh's mother and right beside her aunt. The song first appeared in a scene in Meet Me in St. Louis, in which a family is distraught by the father's plans to move to New York City for a job promotion, leaving behind their beloved home in St. Louis, Missouri just before the long-anticipated Louisiana Purchase Exposition begins. In a scene set on Christmas Eve, Judy Garland's character, Esther, sings the song to cheer up her despondent five-year-old sister, Tootie, played by Margaret O'Brien.
