Since this has turned to a Kansas topic, I will add my .02. Since I am the "Old Lady" on this board

, I saw Kansas during their hey day back in the 70's, with the original members. They played a concert with Cheap Trick, who had not yet broken big.
Anyway, Kansas SOUNDED really terrific. One of the best
sounding concerts I ever heard, but they were pretty static, except for Steve Walsh, who hopped around his keyboard. He almost looked out of place, LOL. Kansas has always been a very symphonic band and the members act as though they are in a symphony. Not much action, other than musical, onstage.
I will say that Cheap Trick came close to blowing Kansas off the stage. They were such a great live band -- two hotties and two nerds, LOL!
