Mr. Gross and his partners ran the theatres and produced the shows in them. The theatres, typically of the in-the-round style, became destinations for stage and concert performers of the first rank, though the level of attraction decreased as the decades went on and the world of summer stock theatre declined. By the 1990s, the theatres had fallen out of fashion. The Painters Mills Music Fair was torn down in 1991, the Valley Forge was demolished in 1997. The Westbury, now owned by Live Nation, goes by the far less whimsical name of The Capital One Bank Theatre at Westbury.
