Guests Cass Elliot & Bernadette Peters. Cass plays the heavy-fasion model Suzie Shrimpton-in "As the Stomach Turns." Will she find true love with underground filmmaker Randy Wahoo? And what will become of Sister Ruby, the tap-dancing nun? The Carol, Cass and Bernadette trio performance of "You've Got a Friend" has a few surprises, but predictably strong vocals enriched by the Mamas & the Papas-styled harmonies.
