It's a dry heat.
Gotta love that "guitar microphone" John Belushi was using (gee, why didn't those ever catch on?), a precursor to the Garth Brooks weird alien face attachment.The Zappa orchestral piece is embarrassingly funny -- those guys thought they were so cool! But it really sounds kind of tame by today standards. I kinda wish Zappa had sung one of his songs instead of just stood there and conducted.
Gee, I liked watching him conduct.
