"I do know that generally they [Pete Seeger and the Smothers Brothers] dominated the media and presented only one point of view."
Dominated the media!?? That, Conrad, is one of the most ridiculous things that anyone has ever said. It more than amply demonstrates that you are either deliberately distorting history or you have no idea whatsoever of what the real situation was.
Pete Seeger was DENIED access to the media for years, and the Smothers Brothers were more of a stand-up comedy act who used parodies of folk music to get laughs. They were hardly famous for their political views.
