David Marks

David Lee Marks (born August 22, 1948) is an American guitarist who was an early member of the Beach Boys. While growing up in Hawthorne, California, Marks was a neighborhood friend of the original band members and was a frequent participant at their family get-togethers. Following his departure from the group, Marks fronted the Marksmen and performed and recorded as a session musician.

Marks joined the Beach Boys in February 1962, replacing Al Jardine on rhythm guitar, and performed on the band's first four albums, Surfin' Safari (1962), Surfin' U.S.A. (1963), Surfer Girl (1963), and Little Deuce Coupe (1963). Because he did not appear on the 1961 single "Surfin'", the first performance by the band that became "the Beach Boys", most historians discount him as a true founding member of the group. In August 1963, he left the band due to personal problems with manager Murry Wilson. Afterward, Marks worked with acts including Casey Kasem's Band Without a Name, the Moon, Delaney & Bonnie, Colours, and Warren Zevon, and studied jazz and classical guitar at the Berklee College of Music and the New England Conservatory.

From 1997 to 1999, Marks returned to the Beach Boys for their live performances. In 2007, he released an autobiography, entitled The Lost Beach Boy. He briefly reunited with the group for their fiftieth-anniversary tour and the 2012 album That's Why God Made the Radio.

At age seven, David Lee Marks moved into a house across the street from the family home of the three Wilson brothers, Brian, Dennis, and Carl Wilson, later the founding members of The Beach Boys. Describing the neighborhood, Marks noted, "It was run down. There were no sidewalks. The houses were older and the Wilsons lived in a pretty small, modest two-bedroom home. The boys all shared a bedroom. When they got older, Brian started sleeping in the den more and more, which was a converted garage they had turned into a music room. They had a Hammond B-3 organ, an upright piano, and a little hi-fi in there."

As the 1950s progressed, Marks sang and played music with the Wilson family at their Sunday night singalongs. Inspired by a 1958 performance by guitarist John Maus (later of the 1960s Walker Brothers), Marks asked his parents to buy him a guitar, which they did on Christmas Eve, 1958. He began taking lessons from Maus, who had been a student of Ritchie Valens.
