There was a similar incident in New York two years ago. My best friend and I were walking in Brooklyn when we noticed an acquaintance from Hollywood, a fellow musician. I wasn't a musician but my friend was.
"Aren't you the keyboardist? Kenny Casio and the Yamahas?"
Sure enough, he was. He was touring New York clubs and he so happened to be gallivanting across the street at the same time on the same day. If my friend were having a spacing fit then he might've missed him, but that would've never occurred anyway. Because of fate. After losing touch for two years, Kenny Casio and my friend reconnected. A year later my friend shot a music video for Kenny and posted it on the major social networking sites. Only if the reunion brought a collaboration of recorded albums and concert dates, well then that would've deserved a documentary.
