The song "Have Yourself a Merry Little Christmas" was originally written by Hugh Martin and Ralph Blaine in 1943 for the movie "Meet Me in St. Louis." Judy Garland sang the song in the movie, and it became a holiday classic. Many other artists have covered the song over the years, including Frank Sinatra, Bing Crosby, and Ella Fitzgerald. The song has become a Christmas standard and is often heard during the holiday season.
