Busking is something starving artists and up 'n' coming musicians do. Buskers perform in public places, like sidewalks and subways, receiving dollars from passersby who are enjoying their music. Well, Justin Bieber is well past the point of needing to busk, but the teen sensation did just that, surprising fans in his native Stratford, Ontario over the weekend. Bieber the Busker? Who knew!

The Biebs held court on Downie Street, outside the Avon Theater, during the Saturday (June 16) matinee of the Stratford Shakespeare Festival's production of 'You're a Good Man, Charlie Brown.' Toronto.com reports that the festival had no clue that the Biebs would show up and entertain.

“We had absolutely no idea he was coming,” Ann Swerdfager, publicity director for the festival, said. Well, if there is one way to generate publicity, it's an unannounced "secret" busking performance by the biggest male pop star on the planet.

The Biebs did not attend the 'Charlie Brown' performance nor did he collect any money for his impromptu public performance, either. He merely sang his early smash 'Baby,' with his fans serving as the backup vocalists and bounced.

What a treat that must have been for local , hometown Beliebers.

It was also a clever publicity-generating move for the 'Boyfriend' singer, who was in town for the 2012 MuchMusic Video Awards. He will drop 'Believe' on Tuesday, June 19.
