When America, Preferred (1941) was filmed, he was a private in the 72nd Air Base Group,
Moffet Field, California.
The gap in credits between 1948 and 1971 tells it all - he was a victim
of the McCarthy anti-Communist inquisition.
He never really recanted his progressive views and in the mid 70s was a
student of Werner Erhard's "est," and wrote a song dedicated to Werner
and extolling "est," which he presented at a monster "est" event at the
Oakland Coliseum.
