I saw the thread, and said, "Hey, I think I do know that song", then I opened the thread and realized that I know about the song because I remembered the thread--

Anyway, maybe we should look for Emmett "Robby" Robinson--Also, it might help to try to find an old Main Point schedule to find the time and date of the John Denver performance--also, it may be possible that
someone somewhere taped the actual performance, so it might be worth checking the John Denver fansites--Excessive? Maybe, but you've been looking for two and a half years, so this has gone beyond being just a casual inquiry, and will continue to plague you til you've found the song--
