Gay Weddings and 32 Funerals: Remembering the UpStairs Erik Ose
"...To fully understand recent events, it's important to remember a tragedy that happened thirty-five years ago, and how much things have changed for gays and lesbians since then.
On the last Sunday in June, 1973, a gay bar in New Orleans called the UpStairs Lounge was firebombed. The resulting blaze killed 32 people. At the time, the bar had recently served as the temporary home for the fledgling New Orleans congregation of the Metropolitan Community Church. Founded in Los Angeles in 1968, the MCC was the nation's first gay church...
That Sunday was the final day of Pride Weekend, the fourth anniversary of the Stonewall Uprising of 1969. Yet there was still no Gay Pride Parade in New Orleans. Almost two dozen gay bars dotted the French Quarter, but gay life in the city remained largely underground...

At 7:56 pm a buzzer from downstairs sounded, the one that signaled a cab had arrived. No one had called a cab, but when someone opened the second floor steel door to the stairwell, flames rushed in. An arsonist had deliberately set the wooden stairs ablaze, and the oxygen starved fire exploded. The still-crowded bar became an inferno within seconds.
The emergency exit was not marked, and the windows were boarded up or covered with iron bars. A few survivors managed to make it through, and jumped to the sidewalks, some in flames. Rev. Bill Larson, the local MCC pastor, got stuck halfway and burned to death wedged in a window, his corpse visible throughout the next day to witnesses below..."
