text:  50 years ago today, June 29th, 1974, one of the world's greatest dancers defected from the Soviet Union. Mikhail Baryshnikov was on tour with the Bolshoi Ballet in Toronto, Canada when he slipped away from his handlers. He spoke about it to our Anthony Mason two years ago on CBS Sunday Morning. Does that seem a long time ago? No, it's been very fast. It wasn't easy for Baryshnikov to defect. You were usually followed by KGB agents when you went, yes?
