I played professionally around San Jose in the 80s and early 90s.I first heard of John from Andy Just and others.Once I was playing a club called The Cabaret and he was the bottom billed act;a year later I found I was opening for him.In the late 90s he was in a band called The Missing Man Formation led by ex-grateful dead/Tubes keyboardist Vince Welnik.I heard he played with Wayne Newton in Vegas.I hope this is helpful!
