@16f4 @larsman - About Kansas City Jammers...
I did a google search and there is a YouTube video of KCJ doing a reunion concert at Gray Chapel at Ohio Wesleyan University (Delaware, Ohio). Here's the description from YouTube. Looks like they are from Ohio...
Jan 21, 2010 The Kansas City Jammers reunited Jan. 16 to perform in Gray Chapel at Ohio Wesleyan University.
This video shows highlights of the bands concert. Members Jasey Schnaars (OWU Class of 1972), Geoff Grief and Bullet Bob Thompson (both OWU Class of 1971) decided to reunite after their early 1970s album gained popularity on the Internet. In April, the Jammers plan to auction a private concert on eBay, with proceeds going to Ohio Wesleyan.
