“So… where do we go from here?” the 73-year-old teased on Instagram on Tuesday.

She said the single – also titled “Where Do We Go From Here?” – would premiere on BBC Radio 2 today.

Singers Faltskog and Anni-Frid Lyngstad represented the double A in the ABBA acronym alongside Bjorn Ulvaeus and Benny Andersson.

While it took ABBA nearly 40 years to return with a new album after the band split in the early 1980s, Faltskog has since produced several solo albums. Her last effort, simply titled “A”, came out in 2013.

ABBA were propelled to global stardom after their 1974 Eurovision Song Contest win with “Waterloo”, but they split in 1982, a year after the album “The Visitors”.

In 2018, the supergroup confirmed rumours they had returned to the studio to record new music.

ABBA finally announced a new album in September 2021 and released the singles “I Still Have Faith in You” and “Don’t Shut Me Down” ahead of the 10-track “Voyage” two months later.

ABBA also made a return to the stage with a London show the following year in the form of projected holograms – dubbed “ABBAtars”.
