Pop fans rejoiced this week as ABBA announced their comeback with a virtual concert and new album - their first new material in 40 years.
If that wasn't exciting enough, member Benny Anderson revealed during the livestream announcement that the record includes a Christmas song.
Perhaps surprisingly, it will be ABBA's first ever festive song. The group never officially recorded a Christmas song, but members have recorded festive music outside of ABBA - notably Benny and Bjorn, who released a Christmas album in their pre-ABBA days as part of rock band The Hep Stars.
In 1981, singer Agnetha and her daughter Linda recorded Christmas album Nu Tandas Tusen Julejus, the title track of which is a traditional Swedish language festive song.
Of course, odds are already on for ABBA to score this year's Official Christmas Number 1 with the track. Luke Tarr, Head of PR at bookmakers Star Sports, said: "ABBA delighted music fans with the announcement that their new album is due to be released in November, and punters have been taking a chance on them reaching the top of the Christmas charts at 8/1."
If they manage it, ABBA could be the latest icons to join the Christmas music hall of fame - previous acts to claim an Official UK Christmas Number 1 include The Beatles, Queen, Cliff Richard, and Spice Girls.
Things are shaping up nicely for ABBA's upcoming ninth studio album Voyage, with a reported 40,000 UK pre-orders since yesterday's announcement. The group launched their comeback with two new songs, I Still Have Faith In You and Don't Shut Me Down. Other songs on the record include I Can Be That Woman, No Doubt About It, and the curiously-titled Keep An Eye On Dan.
To date, ABBA have nine Number 1s on the UK's Official Singles Chart, plus nine chart-topping albums. Look back at ABBA's full Official UK Chart history.
