Mumford and Sons were once accused of people trafficking.

The British folk band nearly missed a show on an American tour after deciding to travel on a vintage train, which was mistaken by police in Texas as a vehicle used to smuggle people over the Mexican border. "In Marfa, Texas, we were pulled over by police waiting for us with cars across the track. They accused us of stowing people away on the train. It was edgy, but the gig eventually went ahead. We swelled the town about fivefold and ended up playing soccer with the police," said bassist Ted Dwane.

The "Sigh No More" hitmakers' favorite part of their job is touring and the highlight of their career so far was when music legend Bruce Springsteen invited them on stage in Belgium. "It was the best f***ing day of my life - unbelievable! The Boss had watched our show, which I didn't know until the penultimate song, when I turned round and saw him in his Ray-Bans nodding. We watched his set from behind the monitor desk, then halfway through 'Hungry Heart' he nodded at us and waved us on stage. He grabbed me round the neck and shoved the microphone in my face. Have I watched YouTube footage? Absolutely. From every angle. I never watch our band, but I'll never stop watching that," singer Marcus Mumford said.
