I also noticed the lack of beardness. I kind of like it more when it's more trimmed...less than what was there during Larry King. I mean, it still looked good and everything, I just prefer it to be shorter. lol.
I have to admit that I wasn't paying as close attention as I usually would be to one of his interviews. It was really early (hey, 9 am is early for me LOL) and in addition to that I had only gotten about 3 hours of sleep the night before. As a result, it wasn't an enjoyable experience trying to drag myself out of bed to view him, but it was worth it.

As I said, I didn't notice much when it came to his nerves, but maybe he was just feeling a bit off. I'm not sure it could have been just the fact he was with Regis...because didn't he meet both of them before? At least that's what I gathered from what Kelly said. Correct me if I'm wrong, because I have no idea. haha.
I also had forgotten he was going to be on Ellen! I got online about ten after 11 am (it comes on at 11 am here) and noticed the announcement, I forget where now lol. But I was like OMG and raced in there in time to hear her say that he was up next. I was like, yessss.... hahaha.
