On a Wednesday night in the middle of July 1969, the Grateful Dead turned up at Longshoreman's Hall to help the Hells Angels bury one of their own. The handbill was pure Angel: hand-lettered, blunt, a "Party in Honor of Gino Heinicke (1946-1969)," one dollar per head, no minors. Heinicke was a "Frisco" Hells Angel, reportedly killed that summer in a clash with a rival club; beyond his name, his dates, and the fact that his brothers threw him a musical wake, the documentary record is thin, and it is better to leave it thin than to invent a life. Underneath his name ran the bill — Grateful Dead, Cleveland Wrecking Co., Ice, and the Brotherhood of Light on the projectors — the ordinary furniture of a San Francisco dance-concert pressed into service as a funeral.

The building itself carried freight. Longshoreman's Hall, the union meeting place out by Fisherman's Wharf, was where the Family Dog had staged "A Tribute to Dr. Strange" in October 1965 — the costumed, strobe-lit night that is as close as anything to the birthplace of the San Francisco scene. To hold an Angels' wake there four years on was to fold the counterculture's origin room around its rougher edges. The Dead's tie to the Angels was real and unsentimental: the club worked the doors and the crowds at Bay Area shows, and the band played their parties in turn. This was mid-1969. Whatever the Angels would come to mean later in the year and after, on this night the relationship was simply a working one, and it should be read that way, without the hindsight the calendar tempts us toward.

What actually happened onstage is where honesty has to do its work, because the record is genuinely thin. No full setlist survives, and it would be easy — and wrong — to dress this night up as a triumphant Dead concert. It was a benefit thrown by a motorcycle club for a dead brother, in a rented union hall, with a light crew and a handful of bands; grief and a rough crowd shaped it more than any performance did. What can be said plainly is small: the Dead were billed, the Dead played some form of set, and the evening belongs to the wake it was, not to any legend we might be tempted to hang on it. A poster survives and trades at auction; the night's deeper texture is mostly lost. That absence is the honest ending here — not a set to celebrate, but a true and tangled night that the sources will only let us see in outline.
