ABBA masterminds Benny Andersson and Bjorn Ulvaeus are all set to unveil the first song they've written together in fifteen years.

The track is called "Story Of A Heart" and is described as a mixture of Swedish folk music, polka, waltzes and Celtic folk, but as it’s the ABBA boys, above everything it is sure to be pop. It features vocals translated into English and sing by Swedish star Helen Sjoholm. The song will be available as part of a fourteen track album by The Benny Andersson Band.

"Story of a Heart" is due for release on July 6th.
