A lot of rumors were floating around but yesterday it was confirmed that Elton John and Fall Out Boy are collaborating on Fall Out Boy's next album Save Rock And Roll. The unlikely duo have been working together in a studio in Atlanta which was officially confirmed via a photo posted to Twitter by Fall Out Boy guitarist, Patrick Stump. The album originally due out in May the album has been pushed up to April 16th because of the success of the single "My Songs Know What You Did In the Dark (Light Em Up)," which has had over 380K downloads. They may be in a rush but it looks like they are having fun!
