Every Monday after they finish rehearsing, members of the Barbershop Harmony Society's Oakville Chapter head down to their favorite Tim Hortons and order a cup of coffee and a donut.
Danfi Parker also frequents the same Timmies, and happened to be there during The Entertainers' weekly visit.
"They had a little whistle thing to set the pitch and then they just started singing," he told the Toronto Star.
Parker said he was caught off guard when the elderly gentlemen first launched into song, but by the time they moved from Sinatra tunes to Elton John's "Can You Feel the Love Tonight?," he was ready with a camera in hand.
"It just goes to show beauty can be captured at any moment in the most random places," Parker said.
