The first season, airing in the summer of 1968, sought to capture a throwback 1930s aesthetic, with costumes and songs inspired by the bygone period. The style was evocative of the streetwise "gold digger" chorus girl films of the '30s, as well as the popular gangster films of that decade (mostly produced by Warner Bros.). The stylistic choice may have been inspired by the popularity of recent box office hit
Bonnie and Clyde (1967), set in the Depression era. The 1969 season expanded its retro aesthetic to include the 1940s war years, and the 1970 season abandoned the throwback gimmick in favor of a more contemporary sensibility.
