I like the Beach Boys, but didn’t Glen Campbell and Carol Kaye play guitar on most all of their records (uncredited)? If Brian was a little nuts, what did that make Spector?
Yes, that's Glen Campbell on guitar on "Good Vibrations," and his guitar break on the original mono version of "Help Me Rhonda" is classic.
A murderer? No wait, that came later.
Spector like Brian Wilson, had this amazing gift to hear music in a way no one else could, and in his case it was the Wall of Sound. Brian was more into the interaction of complex vocal harmonies and those really unusual sounds and tone that he’d combine in unique ways. As soon as he hooked up with Spector and the Wrecking Crew studio musicians, Brian switched gears from being in a band to being a composer and producer, and using the best players in the business. Find a way to see the Wrecking Crew movie or read the book, it’s quite a story. To the musicians it was just good-paying work, but when they worked for Brian they knew it wasn’t just another 45 rpm single.
Carol Kaye played the Bass on Sloop John B. Look on Youtube for Behind the sounds Sloop John B The Beach Boys and you'll see a lot of other well known back then names. Hal Blaine was the drummer. As the band progressed they did more and more of their own work. Carl Wilson was as talented in voice and instruments than Brian maybe more so and Carl was talented as well. BTW there is also a video of the making of Good Vibrations on Youtube as well look for the title The Beach Boys - Good Vibrations - Rare Studio Recording Fil.
Carl and Brian could sound so much alike it was hard to tell them apart. Sloop John B had two versions. The one on Pet Sounds is the one with Brian and Mike Love. But an alternate recording with Carl and Dennis singing it was also made.
The Henry Gross song "Shannon" Carl was going to do the chorus for it and couldn't make it for some reason. That song came from a conversation Carl had with Henry. All of The Beach Boys were good musicians in their own right.
The Wrecking Crew (led by the GREAT Hal Blaine) played on just about all the Beach Boy tracks...and so many other artists. Glen and Carol were long time members of that historic group among many other talented musicians.
Way back when, I saw the Beach Boys in concert that featured Glen Campbell on lead guitar. Glen traveled with them when Brian Wilson stopped touring.
A related side note...on Glen Campbell’s masterpiece “Wichita Lineman” (written by Jimmy Webb), Glen played the solo using Carol Kaye’s 6-string bass guitar he borrowed from her.
