This is what we found on Wikipedia regarding the Step Into Christmas:

"Step into Christmas" is a Christmas song written by English musician Elton John and songwriter Bernie Taupin, and performed by John. It was released as a stand-alone single in November 1973 with the song "Ho, Ho, Ho (Who'd Be a Turkey at Christmas)" as the B-side. Upon its original 1973 release, the song peaked at No. 24 on the UK Singles Chart, and it reached a new peak of No. 8 on the same chart in 2019. In the United States, the single reached No. 56 on the Cash Box Top 100 Singles chart and No. 1 on the Billboard Christmas Singles chart.

"Step into Christmas" was later included as a bonus track on the 1995 remastered reissue of the album Caribou, even though it was released in the Goodbye Yellow Brick Road era. It also appears on the albums Elton John's Christmas Party, Rare Masters, To Be Continued, Diamonds and various Christmas compilation albums. Two versions with different vocals are known to exist: the original single mix and a version recorded for John's 1973 performance of "Step into Christmas" on The Gilbert O'Sullivan Show television programme (which featured Bernie Taupin standing in for Ray Cooper on percussion).

In 2009, "Step into Christmas" was listed as the ninth-most-played Christmas song of the 2000s in the UK.
