I saw the stage production in 1970 in Chicago...I was a HS senior. Still have the Playbill around here somewhere...
I saw the stage production at the Biltmore in NYC on January 1, 1970. I knew a guy who through another guy knew Jerome Ragni and a group of us attended. In February, I was drafted for the third time (they finally caught up with me
). They had an open call for the crowd at West Potomac Park in the movie version. It crossed my mind but I didn't go.
