British singer-songwriter Jamie Lawson was practically unknown when he arrived in New Zealand a few weeks ago. But by the time he flew out last Monday, he had performed to around 40,000 people and had a potential smash hit under his belt, after seeing his single Wasn't Expecting That added to mainstream radio and break into the top five of the iTunes chart.
It's a dream run for a little-known artist. But when you have a superstar like Ed Sheeran on your side, anything is possible.
Lawson was the first signing Sheeran made on his newly established record label, Gingerbread. And the simple act of Sheeran including him as the support on his latest Australasian tour has sent Lawson's profile soaring into the stratosphere.
"It's incredible to have that happen in a week. I can't really take that in. It's just like, the song is number 15, oh it's number 10, oh it's number six, oh now it's number three."
