Sunday, August 3, 1969, is one of those nights the Grateful Dead's own archive keeps circling back to, and it earns August 3 as its own even though it was the second of a two-night weekend. The setting was the Family Dog on the Great Highway — Chet Helms's last venture, the reopened Edgewater Ballroom at 660 Great Highway, at the fog-bound western edge of the city where the surf is loud enough to hear between sets. The bill was the Grateful Dead, with Albert Collins and Ballet Afro-Haiti; Collins, the Texas "Master of the Telecaster," had come in on short notice, and the pairing of his ice-pick blues and an Afro-Haitian dance ensemble with the Dead is exactly the kind of programming the Great Highway room specialized in during its brief life (the weekend is documented across jerrybase, Corry Arnold's Rock Archaeology 101, and the Lost Live Dead post on the run, with dead.net filing the surviving material under August 3).

Two things make August 3 the night rather than August 2. The first is that a board tape survives from it, which is why it lives in the Dead's documented canon at all — the recording is the reason the details of this particular Sunday are recoverable when so many ballroom nights are not. The second is the matter of the guests. On this night, unidentified sit-in players — described in the sources as an electric violinist and a tenor saxophonist — joined the band, including on a "Dark Star" that collectors have argued over for decades. The temptation is to name them; various guesses have circulated (Charles Lloyd and David LaFlamme among them), and Corry Arnold, who is careful about this sort of thing, disputes those identifications rather than endorsing them. So the honest entry is that the guests are unconfirmed — a genuine mystery on a well-recorded night, which is more interesting than any tidy attribution would be. The weekend's poster, FD 69-0801, advertised all three nights the strike had disrupted (August 1 through 3); its designer is uncredited in every source we could reach, and we leave it uncredited rather than invent one.

The context that gives August 3 its weight is the strike two days earlier. The Friday show, August 1, had collapsed when the Light Artists Guild picketed the hall and Garcia refused to cross; the dispute settled within a day, and this Sunday is the far end of that story — the band back on the salvaged bill, playing the run out. To read August 3 without August 1 is to miss half of it; together they make a small parable about the scene in its final year, when even the light-show operators had grievances and a picket line could stop the Grateful Dead at the door.

The other years offer one real event and a set of honest nulls. In 1967, August 3 was the Thursday opening of the Fillmore Auditorium's long Muddy Waters / Buffalo Springfield / Richie Havens run — night three of the six-night BG-76 booking that had opened August 1, the same MacLean poster and the same bill; a real show, but one already anchored earlier in the week by its opening, so it logs here as continuation. Also opening that Thursday, at the Avalon, was the Charles Lloyd Quartet with West Coast Natural Gas on the FD-74 poster (Robert Fried) — a run this chronicle picks up the following day. The remaining years are blanks we decline to fill: 1965 predates the scene; in 1966, August 3 was a Wednesday dark night, with a single-sourced Matrix club booking the only thing listed and nothing at the poster-ballrooms; in 1968, August 3 was the middle night of the Iron Butterfly leg at the Fillmore West and the Pink Floyd weekend at the Avalon, both already carried by their own days earlier in the run, and no distinctly-August-3 event of its own. (One tempting 1966 entry — a Fillmore listing pairing Jefferson Airplane with the Hedds on August 3 — appears to be a mis-dated April show and is left out rather than asserted.)

August 3 belongs to the Dead at the Great Highway: a recorded Sunday with mystery guests and a "Dark Star" nobody has fully explained, at the far end of a weekend a strike nearly erased.
