When does Medical Center return?

Medical Center is an American medical drama television series that aired on CBS for seven seasons from September 24, 1969, to March 15, 1976. It starred James Daly as Dr Paul Lochner and Chad Everett as Dr. Joe Gannon, surgeons working in an otherwise unnamed university hospital in Los Angeles. At the time the show was cancelled, it tied with Marcus Welby, M.D. (which also ran from 1969 to 1976) as the longest-running medical drama on television at that point.
