Sunday in the Park with George was the first Sondheim I saw on PBS in 1986. Then I bought a 3CD set called A Collector's Sondheim which was more or less a career retrospective. Then I got the cast recording of Sweeney Todd, then Into the Woods, then Merrily We Roll Along on CD. My collection has grown over the years. I saw that Lincoln Center production of A Little Night Music. Taped it but lost the tapes.
