Contestant Helen Corwin had been on the show eight years earlier and on this episode, she ended up stumping the panel again.
Herb Alpert & The Tijuana Brass had just performed for four nights the previous week at the McCormick Place exposition hall in Chicago, and nearly losing all their instruments on the last night, January 16, 1967, when the building was destroyed by a fire, despite being thought to be fireproof by virtue of its steel and concrete construction.
Herb Alpert & The Tijuana Brass's first TV special, sponsored by the Singer Sewing Machine Company, aired on April 24, 1967, on CBS. Their recording of the title song for Casino Royale (1967) would also debut that month.
