I'm so glad we went to the concert last night.  In the first half, Shenandoah  has always been one of my favorites (ever since high school), and I often play it with improvised versions on the piano, just for enjoyment.  The folk songs from the late 60's have always rung true to me -- Where Have All the Flowers Gone andSound of Silence, especially.  I have really liked This Land is Your Land ever since I heard Bruce Springsteen's rendition on a 1980's album.  The choral arrangements and variations from the original were interesting, too.  The program relaxed me after a very busy, rushed week.
