I always thought the song AS WRITTEN was directed at Paul Simon -- "sound of protest" v. "sounds of silence."

But there is no doubt that the song AS ARRANGED by Milt Okun takes an additional swipe at Jim (Roger) McGuinn, the Trio's former guitarist.

The back of the VIOLETS OF DAWN LP tells me that the initial of the first name of Carter (who wrote the song with Fred Hellerman) was "S," if that helps identify said person.

I have all the Chad Mitchell Trio/Mitchell Trio vinyl I know of, including their appearances on Belafonte and Makeba albums. Good to know that at least some of it has finally made it to CD.
