He'll show up when he does. He's been turning up about 2-3 west coast time and saying "I guess I caught y'all too late, going to be on here earlier tomorrow night" only to get on around the same time again. Though he did say a few nights ago he would be on around 12:30am, and probably would've been but they were traveling through the middle of the desert and he couldn't get a strong enough signal.
It would make a lot more sense to do these in the day before the VIP Meet & Greets or whatever, before everyone is in bed. That, or get off the West Coast so when you get on at Midnight, it might still only be 10 somewhere else as opposed to 2 in the morning.
