He even joined two girls busking on the side walk for a little song.
I read somewhere that 'Michael Buble was busking and no one cared!' like it was a damn tragedy that there wasn't a massive throng of people around.
First, the streets looked pretty dead. Second, he was crouched down in a corner, I don't think he was begging to be mauled. Third, it's Calgary - you could walk by someone butt naked and they wouldn't pay attention to you. True story.
Side note: Does anyone know who those girls are? Name them in the comments!
