While fans wait in anticipation for Fall Out Boy's new album Save Rock and Roll, the guys are making sure they are working with the best. Exhibit A - the photo that Patrick Stump Tweeted on Wednesday, March 13 of him hanging out in the studio with none other than rock legend Sir Elton John! Elton has been known to collaborate with younger artists, including Eminem and Lady Gaga, so it was only a matter of time until he hooked up with the "My Songs Know What You Did in the Dark (Light Em Up)" band. 

Are you excited for a Fall Out Boy/Elton John duet? Who else is your dream FOB collabo?
