Lawson took the charts by storm with their debut single, When She Was Mine in May 2012.

Lawson's debut album Chapman Square was released in October, and climbed straight into the top 10.

Lawson kick off their UK tour later this year, and they'll be visiting the west country, so they'll love our cider and pies.

Listen to how the band met... 

The band are set for big things in 2013 including a UK tour, album and single release.

But have the band changed since their early success?
