It was written by Adams and Jim Vallance and became Adams' most popular Christmas song. It was originally released on clear, green vinyl with a picture sleeve. It was written and recorded in Vancouver, British Columbia, Canada. No music video was shot for the song. Over thirty years after it was first recorded, the song still receives significant radio airplay each year during the Christmas season.
Document 2: Christmas Time Is Here: "Christmas Time Is Here" is a popular Christmas song written by Lee Mendelson and Vince Guaraldi for the 1965 TV special "A Charlie Brown Christmas", one of the first animated Christmas specials produced for network TV in the United States.

Document 3: A Charlie Brown Celebration: A Charlie Brown Celebration is the 23rd prime-time animated TV special based upon the popular comic strip "Peanuts," by Charles M.

Document 5: Christmas Time (Is Here Again): "Christmas Time (Is Here Again)" (Lennon/McCartney/Harrison/Starkey) is a Christmas song recorded by the Beatles for their 1967 fan club Christmas record. After being slated for inclusion in the planned (but ultimately scrapped) "Sessions" compilation album in 1985, the song finally saw official re-release in 1995 on the "Free as a Bird" single (issued in conjunction with the "Anthology" series), for which it was edited from its original 6:17 to a shortened version of 3:03. The song opens with a light-hearted tune from all four of the Beatles and occasionally cuts to a tale of the Beatles arriving at the fictional BBC house. This part of the song was cut from the 1995 single version. The song then closes with a Christmas greeting from all four of the Beatles. At the end, "Auld Lang Syne" is played on the organ as Lennon reads one of his original nonsense free verse poems.
