Costello falls out
Elvis Costello has recorded a duet on Fall Out Boy's new album Folie A Deux, out on November 3.
Pete Wentz told Absolute Punk: "We didn't want to talk about this before we actually heard the song because it's a once in a lifetime experience."
Costello will feature on the unnamed song along with guests from the band's Decaydence label. Other guests include Debbie Harry, Lil Wayne and Pharrell.
