If Justin Sherfey, 14, had known how to tie a necktie, a gifted musical duo might never have been born. As Sherfey, the reigning Northwest Fiddle champion, waited to take the stage for a local talent competition, he realized he had a wardrobe malfunction. Colby Acuff, 16, had just performed and saw the younger teen fumbling with his necktie. “I didn’t know how to tie it, so he tied it for me,” said Sherfey.
