T.O.D.
My first exposure to Sondheim was the film of WEST SIDE STORY, followed by the movie version of GYPSY.  I loved both of them and I loved the music but I never knew the connection with Sondheim.  WSS was a Bernstein musical and GYPSY was Jule Styne.  When I saw  Forum (the film) I thought it was horrible.  So my first Sondheim revelation was EVENING PRIMROSE, but I felt like I was the only person in the world who watched it.  None of my theater friends had stayed up to watch, nor had my drama teacher, so it was like I had seen this "miracle" that no one else knew about.
