1. March 23, 1973 (Cow Palace SF -- The "Wall of Sound" Sound Test) Like the recent June 3, 2011 show, it was a Morning Dew sandwiched into a PITB>UJB>MD>UJB>PITB pyramid (there was laos a great one in the same pyramid on November 10, 1973 at Winterland a few months earlier)
2. (maybe my alltime favorite) Ocotber 1, 1974 (Friday night) Winterland, San Francisco (the 3rd night of the five night run before the long layoff that followed and at which the GD Movie was filmed (I'm ini it!)). At all those shows, the two "normal sets" were accentuated by an intermediate set of Phil playing with Ned Lagin (see "Seastones" (which we used to call "Dinosaur Music")) Well on Friday night of that run of shows, the Phil and Ned Seastones segment was expanded when after about 15 minutes of Phil n' Ned, first Garcia and then, one by one, the rest of the band walked on and plugged in, and their lengthy space jam finally resolved in a Dark Star (only one verse sung though) which then finally morphed into an anthemic Morning Dew that just crackled with energy.
