ABBA recording new song!

Formed in 1972, ABBA were essentially a Swedish supergroup, consisting of songwriters Bjorn Ulvaeus and Benny Andersson from The Hep Stars and singers Agnetha Faltskog and Anni-Frid Lyngstad, who had scored success as solo artists.

But their joint project completely eclipsed their previous successes. After winning the Eurovision Song Contest with Waterloo in 1974, the band sold almost 400 million singles and albums around the world.

Mamma Mia!, the musical based on their hits and produced by Ulvaeus and Andersson, has been seen by more than 50 million people.

During their most successful period, the band survived marriage break-ups between Ulvaeus and Faltskog, and Lyngstad and Andersson, but they finally called it a day in 1983.

Their final recording sessions, in 1982, produced the hits Under Attack and The Day Before You Came, which featured on the compilation album The Singles.

Their last public performance came three years later, on the Swedish version of TV show This Is Your Life, which honoured their manager Stig Anderson.
