John Joseph Maus, born November 12, 1943, in New York City, New York, known professionally as John Walker, was an American singer, songwriter, and guitarist best known as the founder of The Walker Brothers. He began performing as a child and formed the duo John and Judy with his sister Judith in 1957. Adopting the stage name John Walker, he formed The Walker Brothers in 1964 alongside Scott Engel and drummer Al "Tiny" Schneider, signing with Mercury Records and releasing their debut single “Pretty Girls Everywhere”. Moving to the United Kingdom in 1965 with drummer Gary Leeds, the group achieved major chart success with “Make It Easy on Yourself”, which reached Number 1 on the UK Singles Chart in September 1965, and “The Sun Ain't Gonna Shine Anymore”, which reached Number 1 on the UK Singles Chart and number 13 on the US Billboard Hot 100 in 1966. Following the group's split in 1968, Walker launched a solo career, releasing the single “Annabella”, which reached number 24 in the UK, and his debut solo studio album If You Go Away in 1967. The Walker Brothers reunited in late 1974, releasing the studio albums No Regrets in 1975, Lines in 1976, and Nite Flights in 1978. In his later career, Walker released solo studio albums including You in 2000 and Just for You in 2007. Walker died of liver cancer in Los Angeles, California, on May 7, 2011, at age 67.
