The "song" here is a mere 23 seconds long. However, most likely for those purveyors of Japanese TV born in the 80s and earlier, the rapid-fire scat will get that tinge of nostalgic recognition...and a slight leer on a number of faces.
When I landed in Japan in 1989 for my JET tour, I had already known that late-night TV there could get pretty weird and racy. Case in point: one time I was watching a video in Toronto from Nippon Video which featured a late-night suspense program. Before the suspense began, there was a first-person interview segment in which a pretty woman sitting on one of those Hollywood director chairs was babbling about something. A minute later, the scene faded out and back in. This time, the babbling continued but this time, the woman was completely naked and unfazed. Go figure!
Anyways, one of the slightly more normal programs that was fixture on the Japanese late-night TV circuit was the legendary "Wide Show 11 PM". Broadcast weeknights on NTV from November 1965 to March 1990, "11 PM" was the first late-night variety-and-information program in Japan which had the atmosphere of something that Playboy's Hugh Hefner would have created if he had ever emigrated to Tokyo. According to the J-Wiki article on the show, the hosts and guests covered the news of the day and leisure topics, did foreign location shoots, played games, showed some stuff that was definitely not for the kids, etc. And from the times I've caught the show near the end of its life, it did all that with a certain ring-a-ding style and with a lot of scantily-clad women.
