Seventies supergroup ABBA are to release their first new song in 18 years after stumbling upon a lost recording while making plans for the reissue of their final album "The Visitors."
"From a Twinkling Star to a Passing Angel" will become available in April.
The track comes from a demo recorded around the time "The Visitors" was released in 1981. It will be the first new ABBA recording released since the box set "Thank You for the Music" was issued in 1994, according to RollingStone.com.
The new version of "The Visitors" will also include six previously released bonus tracks and a DVD featuring rare and unreleased footage, including the band's final performance in December, 1982.
The four-piece has never reformed, despite annual rumors suggesting the bandmates are considering a reunion.
They never even came together for their induction into the Rock & Roll Hall of Fame in 2010 - only former couple Benny Andersson and Anni-Frid Lyngstad made the trip to the gala.
