Despite the song's strong, long-lasting popularity, it has reached no higher than No. 4 in the UK's Official Singles Chart, a position that the song occupied for four consecutive weeks from December 1973 to January 1974. As with most Wizzard songs, it was written and produced by Roy Wood—formerly of The Move and a founding member of ELO. The song was famously beaten to the 1973 Christmas number one spot by Slade's "Merry Xmas Everybody" which remained at the top of the charts for five weeks, from December 1973 to January 1974.
Roy Wood sings lead vocals. The backing vocals for the single are by "The Suedettes", augmented by the choir of Stockland Green Bilateral School First Year. The original sleeve of the single credits "Miss Snob and Class 3C" with "Additional noises". The basic track for the single was recorded in August 1973, so to create a wintry feeling engineer Steve Brown decorated the studio with Christmas decorations and turned the air conditioning down to its coldest setting. Wood wore a woollen hat found in Lost Property. The schoolchildren were brought down from the Midlands to London by bus during the autumn half-term to add their contributions.
At the time of the singles' release, Wizzard's contract with EMI was close to expiry. Promotional copies were pressed by Warner Brothers, with whom the band had just signed for future releases. Only then was it discovered that EMI were legally entitled to the track after all, so the Warner Brothers pressings were halted and the record appeared on the Harvest label, but with the same picture sleeve.
Although Wood had arranged for the members of the Stockland Green School choir to sing at the Top of the Pops television recording, their place was taken by children provided by a local London stage school.
With the failure of its first release to top the UK Singles Chart in 1973 - it was kept from number one by Slade's "Merry Xmas Everybody" - it was reissued in 1981 (reaching number 41 on the UK Singles Chart), and then again in 1984, this time with an additional extended 12-inch version, and getting as far as number 23.
As downloads as well as physical sales became eligible for the weekly Top 75 from January 2007 onwards, and with the help of additional exposure thanks to an Argos television advertisement later in the year using an excerpt of the song for a soundtrack, it was one of several Christmas oldies to chart again in November and December 2007. This time "I Wish It Could Be Christmas Everyday" reached number 16, despite the absence of a physical release in the retail shops.
In the week of 13 December 2008, the song peaked at number 31. In the week of 14 December 2009, it peaked at number 45. In the week of 11 December 2010, it peaked at number 46. In the week of 12 December 2011, it peaked at number 28 (its highest position since December 2007). In the week of 16 December 2012, it charted at number 29.
Liz McClarnon from Atomic Kitten said, "When we started the talks for The Big Reunion this time last year, we couldn't have imagined we'd end up recording a Text Santa Christmas single! It's all for charity and we are so humbled to be a part of it!" Michelle Heaton from Liberty X said, "I'm so excited about being involved with the Text Santa Christmas single...After 11 years who'd have thought we'd be performing with such amazing acts whilst raising money for six fabulous charities?" Jimmy Constable from 911 said, "Christmas is our favourite time of year. To be involved in text Santa is an amazing opportunity for which we are very lucky. But most of all raising lots of money for a great cause." Ritchie Neville from Five said, "To be given the chance to help raise money for the amazing charities that ITV's Text Santa appeal help, to bring attention to their causes and the plight of the real people they help, aiding them to make lives better really is the icing on the cake for me after this "Big Reunion" year. And to do it at Christmas time is even sweeter. Do they know it's Christmas? Hopefully they will with Text Santa!!" Keavy Lynch from B*Witched said, "Back in the day we were in competition with each other this time round we get to do one big fantastic single together." Celena Cherry from Honeyz said, "We're so excited we just can't hide it!"
^The four consecutive weeks include one for which no new chart was published; when this occurs, it is the usual practice to repeat the previous week's chart to fill the gap. The same two records - "I Love You Love Me Love" and "You Won't Find Another Fool Like Me" - intervened between the Slade and Wizzard discs both before and after the "gap" week.
^It has been claimed that the choir's participation was arranged by pianist Bill Hunt, who may have been brother-in-law of the school's maths teacher. But a familial connection has been disputed, since Hunt's mother is alimed to have lived in nearby Queens Road, also within the ward of Stockland Green.
