“The Christmas Song” (commonly subtitled “Chestnuts Roasting on an Open Fire” or, as it was originally subtitled, “Merry Christmas to You”) is a classic Christmas song written in 1944 by musician, composer, and vocalist Mel Tormé (aka The Velvet Fog), and Bob Wells. According to Tormé, the song was written during a blistering hot summer. In an effort to “stay cool by thinking cool”, the most-performed (according to BMI) Christmas song was born.

“I saw a spiral pad on his piano with four lines written in pencil”, Tormé recalled. “They started, "Chestnuts roasting…, Jack Frost nipping…, Yuletide carols…, Folks dressed up like Eskimos.‘ Bob (Wells, co-writer) didn’t think he was writing a song lyric. He said he thought if he could immerse himself in winter he could cool off. Forty minutes later that song was written. I wrote all the music and some of the lyrics.”
