Hey there, Church Turtle, I think you may have to widen the parameters a bit. You pretty well listed all the well-known songs that are _about_Indiana.
Popular songs that mention Indiana, or some place within, that I can even think of are "Indiana Wants Me" by R. Dean Taylor and "Little Green Apples" by O.C. Smith (...and it don't rain in Indianapolis in the summertime...). I like both songs but neither one is actually about our fair state.
Being a certified proud Hoosier, I am interested in all things Indiana. So your topic got me searching on the 'net for "songs about Indiana" and "songs with Indiana in the lyrics". Didn't turn up much, but I did find this link that provides clues to some old, old songs regarding Hoosierland: http://americanhistory.si.edu/archives/d5300nh1.htm
You have to scroll down to "Indiana".
Indiana is a great state with a rich history. It just doesn't seem to make it into many popular tunes.
If you know of other songs (that most people are probably familiar with), list them here and folks can vote on them.
