[Watch] Mumford & Sons Debut New Song

Sigh No More may be the name of the fantastic debut album from Mumford & Sons but fans the world over have done plenty of sighing since it's release due to it being their only source of material from the London boys. If you were one of those many fans though, breath a sigh of release because up at the top via Philadelphia's 104.5 FM you can peep the band performing a track titled "Ghosts That We Knew" or just simply "Ghosts". A very happy humpday treat indeed for fans.
