"The All-Night Show" was North America's first regular late-night marathon, running live nightly from after sign-off until 6:00 AM. The format was a montage of old films, clips, episodics, guest appearances and special treats served up by your host Chuck the Security Guard and his cameraman buddies Ryerson Dupont and P.B. Leonard, all of whom had supposedly thrown the station back on-air in the wee hours when management was away.
