Shown at a 2005 Beach Boys Reunion, sandwiched in between Bruce Johnston and the world class a-hole Mike Love, is today's Great Unknown Beach Boy, who hails from De-light Arkansas. He was a crack studio musician with the legendary LA "Wrecking Crew" when he was tapped to replace Brian Wilson on tour in 1964 and 1965.
Here's an excerpt of Glen Campbell's wiki entry:
"Campbell, one of twelve children born in the tiny community of Delight in Pike County, then a community of fewer than one hundred residents, started playing guitar as a youth without learning to read music. By the time he was eighteen, he was touring the South as part of the Western Wranglers. In 1958, he moved to Los Angeles to become a session musician. He was part of the 1959 line-up of the group The Champs, famous for their surf instrumental "Tequila".
Campbell was in great demand as a session musician in the 1960s. He was part of the famous studio musicians clique known as "The Wrecking Crew," many of whom went from session to session together as the same group. In addition to Campbell, Hal Blaine on drums and Carol Kaye on bass guitar were part of this elite group of session musicians that defined many pop and rock recordings of the era. They were also heard on Phil Spector's "Wall of Sound" recordings in the early 1960s.
He is heard on some of the biggest-selling records of the era by such artists as Bobby Darin, Ricky Nelson, The Kingston Trio, Merle Haggard, The Monkees, Elvis Presley, Frank Sinatra, Dean Martin, The Association, Jan & Dean, and The Mamas & the Papas.
He was a touring member of The Beach Boys, filling in for an ailing Brian Wilson in 1964 and 1965. He played guitar on the group's Pet Sounds album, among other recordings. On tour, he played bass and sang high harmony.
Other classics featuring his guitar playing include: "Strangers in the Night" by Frank Sinatra, "You've Lost That Lovin' Feeling" by The Righteous Brothers and "I'm a Believer" by The Monkees."
