Benny and Bjorn writing music for the Eurovision song contest..

ABBA's Benny Andersson and Björn Ulvaeus have composed We Write the Story, with arrangement by Avicii, for the 2013 Eurovision Song Contest in Malmö. The anthem is the main theme for  the Swedish host as well as the music for the grand opening act of the Final. Avicii is a Swedish DJ,
record producer who had a big world wide hit with the song "Wake Me Up".
Apparently they did  work with singers on the song prior to it's  premiere, at the Eurovision contest held in Malmo, Sweden  on May 18,2013. Like a lot of recent
Andersson-Ulvaeus songs it could be described as listenable but not awe-inspiring!
