Remember the other series the late Carroll 0'Connor guest starred on BEFORE "All in the Family"-this is 100% true-I have seen BOTH episodes I am about to mention-He also did an episode of ABC's 1963-1965 science-fiction series the ORIGINAL "The Outer Limits" called "Controlled Experiment" (he played the bespectacled Diemos),and the episode of "That Girl"from first season(1966-1967)called "A Tenor's Loving Care" as an Italian opera singer named Giuseppi.Remember these episodes?AND the episode of CBS'1961-1965 father-son lawyer courtroom drama "The Defenders"(NOT to be confused with "The Defenders"CBS is going to air this fall)in which he was teamed with Jean Stapleton?
