Did Aerosmith play at a March of Dimes event in Grand Rapids MI in the middle 70's?

They use to hold a walk - a - thon, every year for many years of my childhood. It was a long walk, maybe 5 miles, or something. If you finished the walk you were provided with Burger King, a concert, etc. One of these Aerosmith played. Not sure, my memory could be thinking of some other band. If anyone can find out if they played there it would settle whether that was them or not.
