16 Rooms

The story would come from the place first, then the people. In either case, a series of rooms: the suites, hallway, boiler room, patio, parking lot, park downtown, storage room, vestibule, laundry room and, perhaps in the end, the common room. 
In every room, a song, and anywhere from one to six people to sing it. 
The figure of the flaneur, if he's still around, will cue us from one room to the next. Of course, the rooms would have to be sequenced to hook their audience into the cumulative story.
Yes, with the place comes the song, and the voices leading to and from. As before, the passage of time would be highly fluid, as I suppose it always is.
My room, her room, their room, our room.
In the random city.
