hawkeyekid....got a little better version of "On Iowa" for ya. It's a little more up tempo, and I think it sounds a little more like the one at the games. It's also got the actual marching drum line, as opposed to someone sitting at a drum set (I know, I'm a stickler to details like this, but I used to be in a marching band back in the day and I can hear these things) Plus this version just adds a little more energy IMHO.
