I remember this well.
Days after the San Francisco 49ers won their first Super Bowl, thrashing the Cincinnati Bengals, John Madden, then with CBS (which aired the game), appeared on Saturday Night Live. As memory serves, I believe Madden was the host that night, and in this sketch, he interviews members of the Bengals. Series regular Tim Kazurinsky plays coach Forrest Gregg. The cast also includes Eddie Murphy and Tony Rosato.
