The production was performed without intermission.
Marian Mercer was replaced as Olivia by Marcia Rodd a week after the show opened. Rodd appears on the cast recording. It was announced that Mercer left to fulfill a prior television commitment, and she did show up as a regular cast member of a summer-replacement series on CBS, The Dom DeLuise Show, which started in early May.
Rodd had played Viola in another Off-Broadway musical version of Twelfth Night, titled Love and Let Love. That show had opened a week and a half before Your Own Thing, and it closed the day after Your Own Thing opened.
The production was originally announced to open on Thursday, January 11, 1968, but during previews the opening was postponed by two days.
Shortly into the run (but after the cast recording was made), a song titled "Let It Be" was added to the production. This was a solo for Olivia. It was placed between "I'm on My Way to the Top" and "She Never Told Her Love." The song was also included in the productions in other cities and the tours that soon followed, and it was in the licensed version of the show and the published script.
