There are so many SCREAMING maniacs in the audience, that I see no need for Jon to do the screams/jungle noises himself. These women are doing it for him. And it is not only during KTF, but just all the time from till the opening till the end of the show. And when Jon is "shaking his moneymaker" the screams in the audience are so intense that they compensate forJon's not screaming during KTF
