that clip from Oberhausen made me realize that I was definitely in the "wrong" preview
what I've seen was the very first complete show in front of an audience, but it didn't include Stewart
apparently there was a 2nd show in the evning with Stewart as a narrator
the chariot race was cancelled that evening
the horses were too exhausted
(and one stuntman had injured himself during the 1st show)
so, good to have seen a full preview
too bad Stewart's steps are so "secret" even to the people on his website...
