Kentucky Waltz (Bill Monroe cover)

Bill Monroe is rightly known as the father of bluegrass, but he also wrote a number of excellent tunes.  Here is my 3-stringed attempt at Kentucky Waltz.  I'm in a standard DAd tuning but a half step down to C#G#c#.  The first half of the tune is pretty straightforward, with only two chords, but the second half gets a bit more adventurous harmonically.
