To close with my discussion of Shakespeare's songs in light of Stephen Sondheim's discussion of the importance of clarity, simplicity and perfect rhyme in song lyrics (which can be found in the opening sections of his 201o book, Finishing the Hat), here's a link to the Songs page from Shakespeare Online: http://www.shakespeare-online.com/quotes/shakespearesongs.html. Give them a read and you'll wonder if Sondheim based his philosophy entirely on Shakespeare. (One could do worse.) And here's a link to a lovely setting, by John Wilson (onetime principal composer of the King's Men), of a song not found on the page above, from 4.1 of Measure for Measure and usually referred to as "Take, oh take those lips away": http://www.youtube.com/watch?v=65lozTGC0go&feature=related.
