Just when you thought ABBA was best seen on Broadway, one of its singers is preparing for a return to the spotlight.

Reclusive onetime ABBA singer Agnetha Faltskog has signed a new record deal that will lead to her first album in 17 years, reports Reuters. Warner Scandinavia said Wednesday that it would release the singer's CD "My Coloring Book" worldwide this spring.

There's been talk of an album -- which is now described as having an acoustic sound and featuring an orchestra and band leader Anders Neglin -- since last year. Warner released Faltskog's last album, "I Stand Alone," in 1987. Since then, the media-shy singer, 53, has lived quietly on a secluded island outside of Stockholm.

Faltskog shot to international fame and fortune three decades ago with other members of the ABBA quartet -- Bjorn Ulvaeus, Benny Andersson and Annifrid Lyngstad. The group disbanded in 1982 after recording such hits as "Dancing Queen" and "Waterloo," but their old tunes form the score for the hit London and Broadway musical "Mamma Mia."

Together, the group sold more than 350 million albums around the world. Apart, they still sold many millions more.
