Yes Cavett's aticle was very touching.

the clip is very good and fischer seems friendly and humorous.

I think BF looks a little restless though, he probably had some problems mentally even then. I think if he starts  discussing purely chess topics he gets much calmer.

Is there any more US TV interviews of BF around, I would love to see his programmes he made for Yugoslav TV with Dmitri Bjelica or if there is any film of him giving chess lectures while on his 1964 simultaneous tours.

I found this interesting.  It includes a tape of Fischer's appearance on Cavett's show.
