...oops, I hit send too soon.

Erik Darling left in 1961 (and would form the Rooftop Singers) and Frank Hamilton came on and stayed with the group until 1963. When he left, Bernie Krauss joined to stay with them through their final year. Vanguard issued a recording of their 1964 Carneigie Hall concert which featuerd all the players - Seeger, Darling, Hamilton, Krauss with Gilbert, Hellerman and Hays.

I can't remember if the film mentioned it, but the Weaver's first disbanded at the end of 1952 when their bookings dried up because of the Red Scare.   Harold Leventhal got them back together for a Christmas concert at Carnegie in 1955.    The 1980 concert was one of a handful of shows that the quartet did after the shows that were captured in the film. The final appearance of all the original members was at the Clearwater Festival. I was at that show and it was a very informal event with people like Holly Near joining the group onstage. Lee Hays died a few months later.
