May 17, 1977
I can think of half a dozen Scarlet Fires I would take over Cornell, starting with Tuscaloosa 5/17. I love Keith, he's my favorite band member, but I don't like the synth organ he plays on it. He experimented with different sounds in '77, mostly to placate Garcia. It drones on too much for me. I much prefer the grand piano in Fender Rhodes, but he was forced away from those; later in May he retired the Drone organ (would love to know what it actually is - maybe a polymoog).
BEW - May 77 is the time but it's not Cornell.
5/25 The Mosque
5/21 Lakeland (it's either this one of the 19th, but definitely Dick's Picks 29). Cherry exits the solo with swagger and finesse.
Also 11/4/77. I'm pretty sure this is the date. It's the Colgate show from Dave picks 12.
They're all Rock Solid vocally and instrumentally. What sets apart a good for me great brown-eyed women is the solo. In 1977 Garcia stretched it out to three bars in duration. It always improvised it. He nailed it on the three occasions I mentioned.
