On Wednesday, a photo showing Elton John sitting next to Fall Out Boy frontman Patrick Stump was posted by Stump on his Twitter feed , along with the message "#saverockandroll #sireltonjohn."  The pic sparked speculation that the Rocket Man would be contributing to the alternative-rock band's upcoming album, Save Rock and Roll , which is due out on April 16.

Now, reps for Fall Out Boy have confirmed that the legendary pop star has indeed recorded a track with the band at a studio in Atlanta for Save Rock and Roll .  No other information about the new song has been made available.

Last month, Stump hinted to Billboard that there would be "a couple of guests" on his group's forthcoming record, so there may be some more surprise collaborations headed our way.
