I didn't take your questions to be negative, or hostile, or anything like that--and yes, the demon factor on the internet is that we write in a conversational style, but things like tone of voice, which really imparts a lot of meaning in conversation, aren't there--

Anyway, my main point here is that the civil right movement, like the labor movement and the anti-war movement, used songs as tools for building solidarity--the songs were drawn from folk cultures, to be sure, but most of the people who sang them, on marches, at sit-ins, at rallys, etc, learned them as "Freedom Songs" and did not know them outside of that context--the songs were taught to people by organizers, though the singers may not have considered them to be folksingers rather than organizers.
