Mr. Coe had the weird status as a curious footnote in the history of "Saturday Night Live." When the live sketch show premiered Oct. 11, 1975, he was listed in the credits as a cast member. But his name never appeared again, though he was used in nine more episodes. According to accounts, he was cast as a bulwark against the inexperienced younger members of the cast. He mainly played commercial spokesmen and older authority figures.
