How Sweet It Is (To Be Loved By You)

There is some debate about this show in regard to date/venue
Notes:
"The Grateful Dead played Hollywood Bowl on 7/21/74, and one eyewitness places the end-time of that show at about 9pm. It's doubtful, but not impossible, that Garcia flew right back to the Bay Area to catch a late set with Merl. Even if they played together on this date, it almost certainly wasn't at the Keystone in Berkeley, which was headlining Moby Grape, with Earthquake opening. There's also the little matter of "When I Die" (initially designated "Jam #5" as a placeholder title), which appears twice here."
