Cast one of these to a TV, and it’s what that station reads all day.
All stages: what’s on, what’s next, how late.
One stage, close up: the current competition and who’s next.
The same, for the second stage.
The line-up in number order: present, on deck, danced.
Called, waiting, and who still needs to be found.
The announcement queue and who to call next, in reading order.
The dance that’s on and its agreed tempo, for whoever is playing it.
