I saw JohnM perform for the first time a few weeks ago at Farm Aid 2012 in Hershey, PA.  Nice set.  Wish I could have seen him 30 years ago!!  The show reminded me that I have a very cool poster of a concert that he did on Saturday May 14 at the Ft Wayne Coliseum as John Cougar Mellencamp.  I did a little research and found that he performed under this name from 1983 to 1990 and also that there were two May 14 dates that fell on a  Saturday in this time period: 1983 and 1988.  I'm trying to find out if anyone knows for sure what the correct year is for this show.  If you do, I would appreciate hearing from you.  My intent is to try to sell the poster which is very cool, colorful, and in great shape and want to have my info straight before I post on ebay.  If anyone reading this is interested in learning more about the poster, please feel free to contact me through this site or at etter.dan at gmail dot com.
