Dale, I think they are kind of a house band. They are probably listed on the image from the Quinta Live show the other week, posted in this forum.
I had lunch with my friend Pete Davis today (Dorado fillet over mashed potatoes with broccoli and mushrooms in garlic and butter at Babes!!!) and he mentioned he had a brush with greatness the other day. His travelogue is on his
site. That's Pete with Robert Plant, of the Honey Drippers and some other band... what was it called?
From Robert's t-shirt, he's no doubt been hanging out at the Abyss.... he should have gotten the Playa Deal Card for deep discounts.
