He had a role in a regular sitcom, Hello Mom, and small uncredited parts in the movies The Eddy Duchin Story (1956) and The Missouri Traveler (1958). He became a friend of Ritchie Valens, and was an honorary pallbearer at Valens’ funeral. In 1959 the family moved again, to Inglewood, where he made the acquaintance of David Marks and Dennis and Carl Wilson, helping to teach them guitar. He began using the name John Walker at the age of 17, because he was unhappy at how people pronounced his real name.
From 1957 onwards, he worked as singer and guitarist with his sister, as the duo John and Judy. They recorded several singles for the Aladdin, Dore, Arvee and Eldo labels between 1958 and 1962. In 1961, they formed a backing band and performed as John, Judy and the Newports, until the band split up after an engagement in Hawaii.

Maus obtained an ID card in the name of John Walker, in order to perform in clubs around Los Angeles while under the legal age to do so. In 1963, Walker and Engel, with two other musicians, toured the Midwest as “The Surfaris”, although the group included none of the musicians who played on the Surfaris’ records. Walker also released his first solo record, “What a Thrill”, on the Almo label, with The Blossoms as backing singers.
After singing at local venues, John went on to form The Walker Brothers in 1964 along with bassist Scott Engel, and drummer Al “Tiny” Schneider. American singer, songwriter and guitarist,
