I forgot to mention (silly me) my own contribution to the canon of Yeats songs...and that I recorded my pal Barbara Blatner's version of "Song of Wandering Aengus" with my band Urban Myth several year ago...Just my vocals and her piano and we collaborated on the arangement...beautiful song.
You can buy the CD at www.urbanmyth.com if interested. I hope to record it again some day; we did not have much time to work on the arrangement and would probably spiff if up some if we recorded it again...
