[photogallerylink id=52361 align=left]Last year, almost around this time, British folk-rock band Mumford & Sons was telling Rolling Stone that playing the Coachella Valley Arts and Music Festival was the “biggest show they had every played.”

Clad in charmingly disheveled hot weather attire, the cheeky foot-stomping quartet then went on to play a rare acoustic set poolside at the KROQ house before heading to the polo fields to win over thousands of music fans swaying in the desert twilight.

This year, Mumford & Sons might have played an even “bigger” show, in terms of what it means historically.

Last night, the lads had the honor of performing for the British State Dinner at the White House for Barack Obama, celebrity guest, and “big fans,” British prime minister David Cameron and his wife Samantha.

Dining on a gourmet spreads of halibut with brussel sprouts, Meyer lemon steamed pudding with Idaho huckleberry sauce, and Bison Wellington, the event took place in a tent on the South Lawn with an “America’s backyard” theme. John Legend also joined in on the entertainment.

And Marcus Mumford looked dapper in a vest and bowtie rather than a sweaty grey wife beater.

Mumford and Sons, who spent last year on a week-long tour via railroad with Old Crow Medicine Show and Edward Sharpe and the Magnetic Zeroes for the Railroad Revival tour will also be premiering a documentary on the tour, called Big Easy Express, at South by Southwest in Austin, Texas on Saturday, March 17.
