Davson started singing on a whim aged 17, and quickly caught the bug. "When you do something that grabs you, it makes you feel really good."

Davson said it was the right time to make the jump.
"I'm sad to be leaving some of my friends, but it's time to move on. I've got a lot of good memories here, but I'm about to start another really good adventure."
