In response to Singin' Steve and the much earlier post by Folk1234 he was referring to: Yes, the (Chad) Mitchell Trio were consummate entertainers who believed that they could get their point across far more effectively by using humor and satire than by employing more heavy-handed tactics. The fact that they are all excellent singers didn't hurt, either. Their programs were a mixture of political songs, traditional folk material, novelty stuff (Super Skier, The Story of Alice, etc.) and Tom Paxton songs. But they were also quite serious about the politics they espoused through song, and participated actively in the civil rights movement. I didn't list them in my earlier post because I never considered them to be protest singers. They were having too much fun.
