Swedish pop band ABBA is to release new music for the first time in 35 years, they have announced.
They have recorded two new songs, including "I Still Have Faith In You" which will be performed in a TV special in December.
The quartet said they made the decision to make music again as they thought it "could be fun to join forces again and go into the recording studio. So we did".
Band members Agnetha Faltskog, Bjorn Ulvaeus, Benny Andersson and Anni-Frid Lyngstad said "it was like time had stood still" and it was as if they had only "been away on a short holiday".
"An extremely joyful experience!" they added.
The band said they had enjoyed their hologram tour project so much, it gave them the idea to make some new music.
