[deleted] Rick Derringer. I saw him live once. Oddly enough he was supporting Cindy Lauper. I think Eddie Money was the opener.
Besides being the lead dude in the McCoys (Hang on Sloopy 1965) he was a prominent record producer. Hooked up with Johnny and Edgar Winter for his own mastery and also played on many records with other well-known artists. Google him. He was well connected. RIP.
