I'm stuck in a traffic jam at the moment - my wife is driving, so its ok to post to Mudcat while 'travelling' - and I've just been listening to the Nancy Karr/James Fagan version of 'Locks and Bolts' and mentally comparing it the Martin Carthy's version. To me (personal opinion only) the NK/JF version illustrates what I meant above: they have worked so hard to make the arrangement interesting and sophisticated that they have rather lost track of the song. It's high quality, of course, but for me it doesn't quite work.
