In the latest MUSICALS podcast EDWARD SECKERSON talks to playwright and book writer JOHN WEIDMAN who collaborated with the late, great Stephen Sondheim on three of his shows - Pacific Overtures, Assassins, and Road Show - and was in London for a long-awaited revival of the first of them. Chatting in the bar of the Menier Chocolate Factory the morning after the first preview he reminisces about an extraordinary working relationship where making good theatre was always front and centre of their objectives.
