Judging by recent interviews, Mumford & Sons are inching closer to announcing the follow-up to their breakthrough 2009 album, ‘Sigh No More.’

"We are in the final stages, we're not finished, we don't quite know the exact track listing," keyboardist Ben Lovett told MTV News several weeks ago. "But we have kind of road-tested some songs, and we have picked up some new songs and dropped some ones that people might have thought we were going to be putting on the record. We just want to make a record that's cohesive and one that we feel represents us best right now."

The rollicking U.K. folk-rock band has been debuting new songs during live shows and radio sessions for much of the past year. The song 'Home' surfaced in June 2011 during the band’s stop at the Denver, Colo. radio station KBCO, while the quartet debuted a tune widely considered to be named 'Ghosts That We Knew' at Philadephia, Pa.’s WRFF in November 2011.

Mumford & Sons also played the latter song during their appearance at the Secret Policeman’s Ball on March 4 in New York City. The benefit for Amnesty International also featured a performance from Coldplay and comedy from people such as Jon Stewart, David Cross and Eddie Izzard.
