Betamax "Show Time!!" demo tape

Circa 1983- this was put out by Warner Home Video, but has many promos for Sony electronics and most of the movie clips were from United Artists movies, which Warner distributed in some countries but not in the US- they were put out here on MGM/UA or CBS/FOX Video. (The movie clips have been cut from this upload.) Also strange is that this tape is in linear mono, when Beta Hi-Fi had just come out and is one thing promoted here, along with the then-new CD (Compact Disc) format.
