I was there. A few stood out as having the potential to replace Scott Hennen. I can't recall all their names, however. I thought some tried too hard to be Hennen rather than being themselves.
As you might expect, there were some who shouldn't have bothered trying out, but they get an "Atta boy!" for making the effort. I probably would have fainted before getting through the first sentence.
The judges were Hennen, Tim Hennessy, Pat Sweeny, Cary Eades and the woman who heads Sioux boosters (sorry, I can't remember her name). Tom Bunning and Brad Berry were there, too.
