Listen to The Christmas Song (Stop Video First)

The Christmas Song, commonly referred to as Chestnuts Roasting on an Open Fire or Merry Christmas to You, is a classic Christmas song, written by vocalist Mel Torme nd Bob Wells. According to Torme 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.

Nat King Cole peaked in the Top Ten with the million-seller The Christmas Song (Merry Christmas to You) (music by Mel Torme, lyrics by Robert Wells), which became a perennial hit and is notable as the first instance in which Cole's vocal was backed by a string section as well as the trio. In 1974 the recording was inducted into the Grammy Hall of Fame.
