      The season remembered for Steve's infamous mustache would feature two full-blown crossover epics with The Bionic Woman, starting with the shows’ joint premiere, “The Return of Bigfoot” and culminating in the three-part adventure “Kill Oscar”. Running for 22 episodes during the Fall of 1976 to the Spring of 1977, Season Four would wind up edging out Season Two for the most episodes in syndication. Season Four would introduce what would perhaps be Steve’s last great nemesis, the Death Probe. A Bionic Boy would be created. The show intro would see its final revision, with Martin E. Brooks joining Lee Majors and Richard Anderson (who would gain a new shot of himself on the red phone) in the opening credits, but would remain otherwise the same, Steve's new look not being included in the revised credits. Austin's/Major's mustache would not survive to the end of the season, being shaved off towards its end, though not before starting to tentatively appear on some merchandise, including an issue of the Six Million Dollar Man comic book and a lunchbox. After nearly a year of turmoil after the passing of Oliver Nelson, the show would settle down musically for Season 4 with veteran composer J. J. Johnson, who would lend the year a distinctive sound, and also revive a number of Nelson's earlier compositions for the show in episodes like The Thunderbird Connection and The Infiltrators. Replacing Producer Kenneth Johnson (who would continue on The Bionic Woman in that capacity) was ret
