This livestream is not up and running yet, so you won't see anything unusual if you go to their YouTube Channel right now. (Except that they do have a lot of great videos.)
If you are watching from the USA, you will need to be awake in the wee early hours of the morning to see this event on their YouTube Channel. Adjust for your time zone in the USA if you'll be setting an alarm to get up for this, as I will.
