One take from the Guild Orgy Photo Session
My recollection is that Dan had just met Fred Hammon, of Dark Star pickup fame, and this is instruments from both of their collections. I think Fred is in the back corner, holding the Hagstrom in place. The "Phil Lesh" M-85 is the blond in the back row. It has been discussed before, for example
here, but Rick Suchow's website is being reconstructed so the story is not immediately available.
"Carry It All" was also discussed at the summit. It can be played at

Note that Dan was playing a basically stock Starfire II which is a different beast from the Starfires of Casady and Lesh with the "proto-Alembic" modifications.
I'm going from memory so there may be corrections but...
