I gleaned this from the Mighty 1090 KAAY page on Facebook. The original query from Barry Mac was, who were these people? I think it was settled that this was Pure Prairie League, with the lady in the middle with the mic being Yvonne Day, an overnight news person on KAAY back in 1978, when Russell Jones got there. Word is that she's working in Denver now.
Thanks to Barry Mac for this picture and to Ron Pitts for the identity of the folks and lady.
