Steve Martin is recalling a fond memory of Diane Keaton following her death at age 79. Martin, 80, took to Instagram on Sunday, October 12, to share a photo of a playbill from Santa Ana College's 1964 production of Carousel. Keaton's name was circled under the list of leads, although she was listed as Diane Hall - her father's surname. (Keaton took her mother's maiden name after joining the Actors' Equity Association, as there was already a Diane Hall registered with the organization.) Elsewhere on the playbill, Martin's name was circled under the list of building crew members.
