Thanks, all. Yeah, he was pretty surprised. He lives in Iowa now and is still hanging in there but definitely struggling with health issues. He's about 15 years older than me and we had a couple of bands together in the 90's before he had to stop playing. Here's another one of his; this one was getting some airplay on KSHE-95 in St Louis and surrounding stations back in the early 70's
