Yes, Glenn played lead guitar and bass on so many hit records over the years before he hit it big as a solo artist. Some that come mind are many of the Beach Boys hits including “Good Vibrations” (yes, that’s Glenn’s guitar there), “Viva Las Vegas” with Elvis and so many more. He is one of the most underrated top guitarists of all time.
He had an enormous amount of hits over the years, mostly on the country charts. One “lost hit” from the 1970s is “Southern Nights” which topped the pop charts in 1977.
