Part two of our visit with Dean Ken Womack of Monmouth University.    This week, we look into the value of interpreting and analyzing Beatles lyrics as poetry and the thin line between popular culture and "high art" (and whether such differences should exist).    Once that line is established, the Beatles walk all over it with their pantomime version of "A Midsummer Night's Dream."     We then discuss how "the brand" plays today, as young people hear the music in a piecemeal fashion, with the chronology we all once though so essential ending up as merely another bit of the story.
