Elaine,
I am going to both Villa Montalvo in Saratoga and the Mystic Theater in Petaluma. My friend Gene Smith may be going to the Snoqualmie concert, but I'm not sure. He and I play in separate bands that play a lot of Acoustic Alchemy songs, though certainly nowhere near as well as the originals. Hopefully our whole band (and spouses, etc) will attend the Petaluma show since this is closer to where we live.
