O'Connell continued appearing in choice character parts on both television and films during the 1960s, but avoided a regular television series, holding out until he could be assured top billing. He appeared as Matt Dexter, an aging Irish drifter in the episode "Songs My Mother Told Me" (February 21, 1961) on ABC's Stagecoach West series. In the story line, Dexter witnesses a shooting and is sought as a material witness to a crime. Two Criminals, one of whom is played by Richard Devon, also seek Dexter's whereabouts to make sure that he never testifies in court. Young Davey Kane, played by Richard Eyer, sneaks food and clothing to Dexter, who kills a rattlesnake that had threatened Davey and his dog. Dexter also teaches Davy new songs on his harmonica; hence the title of the episode.
