Folk rockers got in trouble while on the 'Big Easy Express' tour in 2011

Mumford and Sons have revealed that they almost found themselves in trouble with US border patrols last year after they were accused of trafficking illegal immigrants into the country.

The folk band, who toured across the US on a vintage train alongside the likes of Edward Sharpe & The Magnetic Zeros and the Old Crow Medicine Show as part of the ‘Big Easy Express’ tour, were collared by police in Texas, who believed that they were using the vehicle to smuggle people over the Mexican border.

Speaking to The Sunday Times about the incident, bassist Ted Dwane said: ‘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.”

He continued: “It was edgy, but the gig eventually went ahead. We swelled the town about fivefold and ended up playing soccer with the police.”

Mumford And Sons release their new album ‘Babel’ on September 24. The album is the follow-up to the quartet’s hugely successful debut ‘Sigh No More’ and has been produced by Arcade Fire/Coldplay collaborator Markus Dravs, who also worked with the band on their first album.

Speaking about the record, the band said: “As a band, we’ve never been closer or more collaborative, all working to our strengths. And so we feel that this record is a natural progression that we’re proud of, and we cannot wait to take it out on the road.”

Mumford & Sons headline the iTunes Festival at London’s Roundhouse on September 24.
