KSTP, Minneapolis, was the earliest air check I could find on M.G. Kelly.  I do know, after about a year at KTEN in Ada, he was hired by Oklahoma City's KOMA, then performed briefly in Cleveland at WGCL before heading to The Twin Cities. 

If anyone has a copy of a M.G. Kelly broadcast prior to KSTP, I'm almost positive Kelly would like you to set fire to it.

KSTP in the Twin Cities was a remarkable station, featuring a bunch of guys just having fun on the radio.  The Gunner was part of the team that drove KSTP from 16th to #2 in 100 days.  

He was turning 21 while this show was on the air.
