Peter Rowan & Tony Rice have been buddies for a while but the addition of Bryn Bright and Sharon Gilchrist had these bluegrass legends reaching new heights.  The quartet laid down a wonderful version of  "The Free Mexican Airforce," though not before Rowan divulged an entertaining explanation of the song's enlightened origins (Apparently wings aren't always necessary for flying.)  Rowan then joined old friend Junior Brown during his set for a few tunes later in the afternoon.
