I think I already know the answer but it cant hurt to ask here anyways:

Does anyone have a online copy or maybe an old VHS tape of any of Shimizu Senseis TV apparences?
I've seen stills from two seperate TV-apparences but I have virtually no details on them, except that the latter of the two was shot in 1977 at "NHK" (studios?). The latter features Shimizu, Yoneno and Hiroi sensei. Dont know the name of the program he was on though.

Would be very interesting to see those clips.
