"My father was a builder and my mother was a kindergarten teacher, and we had the benefit of a really strong, sporting and farming community, and that's what drove the culture of the town," Clarkson said. Clarkson also attributes his love of football to his "second father", Oscar Harrison, who taught him to "yabby, shoot, and kick a footy", and took him to his first VFL match, the 1977 Collingwood-North Melbourne grand final.
