Stage Review: Sondheim's 'Frogs' is ribeting musical

Post Gazette: "Written by Sondheim in early midcareer, with a book by Burt Shevelove, with whom he'd worked on the similar 'A Funny Thing Happened on the Way to the Forum,' 'The Frogs' first went no further than a 1974 student show at Yale that included Meryl Streep, Sigourney Weaver, Christopher Durang and Larry Blyden. But in 2004 it was extensively rewritten by Nathan Lane, who starred alongside Roger Bart in an elaborate Broadway production at Lincoln Center."
