Homeless Dance Number

Ten tapes found, over the course of fifteen years, in various hidey-holes of the US

Tape #10) location unknown, time/date unknown. The camera's operator is clearly audible, as is some sort of strange, haunting music (some claim it is Beethoven played backwards). The dialogue is repeated below, with the view in brackets.

>camera shakes slightly, as a tripod(?) is deployed, for steadying purposes<
".. set up yet?"
"Yeah, we're good. How many tonight?"
>pause as the camera skips forward a moment, the tripod moved to a window, looking to a broad parking lot, ringed in what appear to be shopping carts<
".. two, maybe three hundred. More than last time. Way more."
"They gonna do it?"
> cigarette is passed in front of the camera, to the operator<
>drag is inhaled<
"Yeah."
>voice is heard off-screen<
"Chips and dips are here. We got beer?"
"We got the beer, pretty lady. You wanna watch them?"
>pause, something muttered<
"They're weird, yeah. But, it is kind of cool."
>someone says something, spoken rapidly, hushed tones<
"What?"
"... starting. Look!"
>camera focus goes out for a moment, zooming into the parking lot below; all the lights in the room are turned off, and all voices go silent<
"... I think it'll be better than last time. There's, like, way more than before."
>something below moves, shadows flickering<
"Cue the lights."
>someone snickers off-camera<
"Dude. This is so cool."
"Shut up."
"... ay."
>in the parking lot below, three hundred or more homeless and vagrant-types are gathering into a rough circle, as the music continues to warble from somewhere off-screen<
>camera shakes; an apology is muttered<
"Shh!"
>camera shakes again; the picture is now in focus: in the parking lot below, the homeless have paired off in what could be described as the beginning of a massive square-dance. Within minutes, it evolves into a full-scale ballroom dance, then a foxtrot, then a minuet, a swing-dance competition and a flamenco-style dance<
>during the dances below, questions are raised as to the style in use; answers are provided from one of five different people in the room with the camera<
>music fades<
"They're done?"
"Yeah. They usually do a few others, but they haven't done that.. what was it? Spanish one."
"Flamenco."
"Yeah. That's new."
"Been watching long?"
"Yeah. When it was two of them, doing a ballroom-thing."
"When was that?"
"Two weeks ago. Every other night, they get together, and do this."
"Ever wanted to catch them at it, like down in the parking lot?"
"No."
"How come? You afraid they'll give you homeless diseases?"
"No."
>camera shakes; sounds of someone being slapped twice -- not for damage, more for effect<
"What did you say it was?"
>female voice, chuckling<
"Dude. What the hell is with the slappin' and all?"
"You had it comin'. We don't break their parties up. No."
>muttered commentary off-screen<
>the homeless have departed, scattering quietly<
"What was that?"
"I said it's 'mysterious and reassuring'. That's what we call it."
