For the nostalgic 1971 Broadway revival conceived and produced by Harry Rigby, Burt Shevelove freely adapted the book from the 1925 original. While the 1925 book was considered quite racy at the time of the original production, Shevelove wrote from a nostalgic perspective, depicting the 1920s as a time of innocent fun. He made extensive changes and cuts to the book, but most of the original score was left intact, with only a few cuts and interpolations. The cast featured veteran screen star Ruby Keeler and included Helen Gallagher, Bobby Van, Jack Gilford, Patsy Kelly and Susan Watson. A young Ed Dixon was in the ensemble. Busby Berkeley, nearing the end of his career, was credited as supervising the production, although members of the cast and crew later stated that his name was his primary contribution to the show. Among a number of extensive dance sequences, Keeler – who returned from retirement for the production – was lauded for energetic tap routines incorporated into "I Want to Be Happy" and "Take a Little One-Step". Rigby's acrimonious relationship with fellow producer Cyma Rubin led to Rubin's terminating Rigby's contract and removing his credit as co-producer, but insiders claimed he deserved full credit for the show's success. Rigby later accepted a $300,000 settlement from Rubin.
