16 May 2011, The Spectator (Hamilton, ON), “Buskers sing a market song: A chance to shine on Ottawa Street” by Meredith MacLeod, pg. A5:
Jeff Lange also took a shot at getting a spot in the market’s busker rotation. He’s fighting a cold and a frequently out of tune guitar but manages a joke while tuning. “What do you get when you drop a piano on a minor?” he asks, directing the punchline at nine-year-old Dakota Bristol, a son of one of the market vendors who’s acting as a judge.
 
“A flat minor,” Lange deadpans.
