Glenn Gould discusses his chair

A staged clip wherein Glenn obviously feels some need to comment in formal terms upon the simple matter of the unusual --and low-- folding chair that he always used whilst playing.

Not much explanation in this short clip, unfortunately, but we get to see him set it up and drop hints about the importance of the thing as implement, as well as allude to some obvious long-term annoyance with people's bewilderment regarding it.
