Sorry, Seany, I can't contribute from lack of knowledge but I want to say that I have often profited much from Mudcat discussion abotu song.Dave (zander), I disagree. In some cases (not in all cases, I admit), knowing about the background of a song or knowing what it was about has even helped me to sing it slightly different in inflection, phrasing, tempo etc. For instance, since I have learned here, that 'Johnny I hardly knew you' was not an anti-war song, as I had wrongly presumed, but a spiteful song by a left lover, I haven't sung the song in the same way as before.
