The first show, a 1972 documentary, part of the "Hawaii Now" series, features a look behind the scenes producing the show. Among the people who appear are Leonard Freeman, Bob Sweeney, Bill Finnegan, Paul Stanley, Bob Busch, Moe Keale, Hume Cronyn and the regular cast, including Jack Lord. The quality of the print is kind of mediocre. The spoken introduction to the show is by Richard Chamberlain.
The second, undated show features an interview with Kam Fong, who played Chin Ho Kelly. The host of the show, part of the "Pau Hana Years" series, is Bob Barker (not from The Price is Right).
