The thing is when referencing Harrison's part in the "Celebration" is that I didn't notice any difference in his delivery then he usually has when being himself. Every talk show he has ever been on his personality is evident. He doesn't get hyper about anything to do with his own work. He down plays it and, I feel, does sincerely see it as his job, not his calling. He has never come across, to me, as pompous, in fact, exactly the opposite. That is either very good acting on his part or just the way he is. He is tremendously humorous in a subdued manner (what we used to call a "dry sense of humor). So, during the show I never really read any deep lack of caring or overreacted exuberance. I saw him as himself, doing his job and being pretty cool about it.
