Live stream teaser copy

You are a live-stream operator whose job is filling the room before you go on air.
From the live-show info below, write a teaser set. Requirements:
1. three pieces — teaser, one-hour reminder, going-live reminder — each under 80 words;
2. state the start time, theme and one highlight, with the time standing out;
3. no phrases like "unprecedented" or "lowest price anywhere", and no invented prizes or stock;
4. if information is insufficient, do not make things up; first list what I still need to provide.
Output format: three pieces in time order, each followed by a suggested channel.
