I like the energy and determination in BB's songs. And the note of confidence always there, in the eventual triumph of the oppressed.
RE the Internationale, his version must be viewed only as a "complement" to the original. The original was written with a clear sense of the struggle between the workers and the capitalists, that is, it is a class anthem. The BB version has, at every important juncture, removed the class theme and replaced it with "the people" theme. Which may be radical but has lost the social stance of the original. IMHO.
