Song written by Noddy Holder and Jim Lea. A big Christmas hit for Slade in 1973, it was covered by Kim Wilde in 2013.
Holder and Lea, members of the band Slade, wrote the song based on melodies from discarded songs written six years before. Released in 1973, it became the band's sixth number-one single in the UK. It earned the UK Christmas Number One slot in December 1973, beating another Christmas-themed song, Wizzard's "I Wish It Could Be Christmas Everyday", which reached fourth place. By mid-January it was still at number one; it stayed in the UK Singles Chart well into February 1974. It sold a million copies upon its first release. It is Slade's last number-one single, but by far their most successful.
The single was certified UK Platinum by BPI in December 1980. Since 2007 and the advent of downloads counting toward the UK Singles Chart, it has re-entered the charts each December. Therefore, it has sold 1.21 million copies in the UK as of December 2012.
