While I do think it is important that a singer of a folk song should think about its roots, I don't like the idea that there is a way that folk songs "should" be sung, I don't accept that the contemporary songs of MacColl are truly folk songs, and I'm buggered if I can see the relevance of Stanislavski technique or Laban theory to the singing of folk songs in that they are exemplars of artsy-fartsiness and thus the antithesis of folk arts.
