Shot by crew member Brett Babcock, this tape was provided by camera operator Bob Erbeck. It's a backstage look at the taping of the last episode of season four from "One Day at a Time", which was recorded live at Metromedia Square on Stage 1 in Hollywood on March 16, 1979. In this are cast members Bonnie Franklin, Mackenzie Philips, Pat Harrington, and Valerie Bertinelli; executive producer Jack Elinson (and it was his last day on the series), producers Dick Bensfield and Perry Grant, camera operators Bob Erbeck and Vito Giambalvo, director Alan Rafkin, associate director Selig "Pinky" Frank, as well as other staff and crew members. A really fascinating look at how a Norman Lear sitcom was produced in the 1970s. Metromedia Square has since been leveled and a high school now stands in its place. Thanks again to Bob Erbeck for this video!
