Standing in one straight uniformed line, the guys of Mumford & Sons stomped their way through a performance of “I Will Wait” off their GRAMMY-nominated album, Babel.

There was no circus performers or backup dancers to be seen; instead the English foursome just played their hearts out.

Singer Marcus Mumford, all smiles, of course, strummed his guitar and played the lone kick drum. The horn section also added a little more sass to the downhome performance. While the light behind the band was so bright, the audience needed shades.

Mumford & Sons, who earlier took home the award for Best Longform Video, made a name for themselves in 2011 with a banjo-filled performance of their song “The Cave.” They joined Bob Dylan for an all-star version of “Maggie’s Farm” with help from the Avett Brothers.

The band also took home the night’s biggest award Album Of The Year and got bleeped while doing it.
