They were singing the last lines of “She’ll be Coming ’Round the Mountain” as they entered. Turned every head in the place, they did. Didn’t take long to realize why: “That’s something you don’t see – or hear – every day,” Pete noted. Not just that a grandfather is singing with his grandchild, Ray added.
