The story behind the song, 'Have Yourself a Merry Little Christmas'.

It was first performed by Judy Garland in the 1944 MGM musical Meet Me In St Louis', for the now famous scene in which she and her seven year old sister, played by Margaret O'Brien are downcast about the prospect of moving away from their beloved home.

Garland asked the composer, Hugh Martin to modify his original lyric, explaining it to be too depressing for her to sing, or the audience to hear.

Martin's collaborator and friend, John Fricke, explains the importance this song had for the composer and the joy he experienced in hearing it covered by every major artist since, from Frank Sinatra to Chrissie Hynde, Punk band Fear to Cold Play, Rod Stewart to James Taylor.

It's clear that the song's enduring power lies in a beautiful melody with a melancholic feel that sums up our emotional ambivalence to the Christmas season.

We hear from those who have a special connection to the song.
