Old friend,
I'm not sure Mr. Seeger was any sort of Communist at all.
This is a man who wrote an idealizing song lyric
with chorus lines like
"and I was never alone,
"and I was not far from home..."
floating in a small boat
in the badly polluted Hudson River,
before the big clean-up.

Where did he get that capacity to visualize an ideal
with pollution literally floating the boat he was on?
