Passenger has come a long way since the release of his first album, Wicked Man’s Rest, back in 2007. The initial incarnation, in which Rosenberg was backed by a full band, was followed by his reinvention as a solo artist and a period of busking, largely in Australia and New Zealand. Then came a year touring the world in support of Ed Sheeran. And then Let Her Go – followed, Rosenberg smiles, by ‘two years running round the world after that song’. He had to run fast: the song, for which Rosenberg won an Ivor Novello, has reached two billion plays on Youtube.
