The group - Andy Brown, Ryan Fletcher, Joel Peat and Adam Pitts - can be seen showing off their toned chests and more in a hot new centrefold for the August issue of Cosmopolitan, with only their instruments to cover their modesty.
And lead vocalist Andy knows all too well how vital it is for men to check their bodies for any changes that could need medical attention.
"It's so important to be aware of your body and any changes," he said. "When I was 19 I had a brain tumour removed. It wasn't cancerous but I lost the hearing in my right ear because of it.
"We named the band after Dr Lawson, the guy who operated on me. He's a legend. If you catch things like this early, it can save your life. It changed my whole perspective on everything."
If you fancy getting your hands on a copy of this sexy centrefold, it appears in the August issue of Cosmopolitan, which is on sale 4 July and available on Apple Newsstand.
Lawson posed for Cosmopolitan to raise awareness of male cancer for Cancer Research UK. Behind the scenes footage can be viewed at Cosmopolitan.co.uk
