The folk group, who are currently touring North America, debuted the track during a live session for Philadelphia radio station Radio 104.5 FM.

The track is the second one in recent months that the band have debuted during a radio session, after they premiered another new song, which is provisionally titled ‘Home’, during a session at a Colarado radio station earlier this summer.

Mumford and Sons are thought to be aiming to release their second album in 2012, but will next release a new song ‘Enemy’ as part of the soundtrack to the new cinematic adapation of Wuthering Heights, which is released this month.
