Honoring a Legacy: Sondheim’s ‘Forum’ at Barnsdall Supports Glioblastoma Foundation Broadway’s greatest farce is a nonstop laugh fest combining vaudeville with the ancient Roman satires of Plautus, a founding father of the situation comedy. With music and lyrics by the late Stephen Sondheim, A Funny Thing Happened on the Way to the Forum tells the story of a crafty slave who strikes a deal with his master to win for him the girl of his dreams in exchange for freedom. As his desperate schemes mount, a never-ending comedy of errors unfolds with plot twists, mistaken identities, and of course, beautiful showgirls. Featuring Sondheim favorites and good, clean, dirty fun, this limited engagement in the heart of Barnsdall Art Park benefiting the Glioblastoma Foundation boasts a comedic ensemble from TV, film, and theater that will leave you applauding for more “Comedy Tonight!”
