Yeah, it was. In fact, he played on a lot of Mike Post's TV show themes. IIRC, he met Mike Post on some sessions with the Wrecking Crew.
I like Mike Post's writing and over the years have transcribed a few of his tunes.
I couldn't believe it when I stumbled on him posting on Facebook a couple of months ago where he is very active talking/posting stuff about his career.
(there is a wealth on good info on there).
It's amazing that he had just crash landed onto Social Media after all these years!!
