I must admit to never really taken to Joan Baez, although I heard her duet with Dylan on the Rolling Thunder Bootleg CD and she sound all right. As for MacColl, he was a great songwriter (in the folk tradition)and a good singer (if a little mannered.)However, he was no Dylan. Dylan did not have a good voice but he wrote songs to accomodate his limitations and my God, what songs they were, and his recordings are nearly always the definitive versions. MacColl was good; but Dylan strode the folk/blues/rock world like a colossus
