Chicken on the run, baby

The story:

I was driving my brother now 46 in my car and he was telling my fiance how much I loved music as a child. He said "remember how much you loved R.E.O. Speed wagon? I remember that song that you used to sing all the time, Chicken on the run?" I could not figure out what song he meant so he sang the lyrics to me. When I corrected him he was so horrified because for about 20 years he was singing those lyrics! Good thing that his cover band rocks a bit harder than R.E.O speed wagon!
