John Marshall Alexander, Jr. (June 9, 1929 – December 25, 1954), known by the stage name Johnny Ace, was an American rhythm-and-blues singer. He had a string of hit singles in the mid-1950s. He died of an accidental self-inflicted gunshot wound at the age of 25. 　　Alexander was born in Memphis, Tennessee, the son of a preacher, and grew up near LeMoyne-Owen College. After serving in the U.S. Navy during the Korean War, he joined Adolph Duncan's Band as a pianist. He then joined the B. B. King band. Soon King departed for Los Angeles, and the band's singer, Bobby Bland, joined the army. Alexander took over vocal duties and renamed the band the Beale Streeters. He also took over King's radio show on WDIA. 　　He began performing as Johnny Ace. He signed with Duke Records (originally a Memphis label associated with WDIA) in 1952. His first recording, "My Song", an urbane "heart-ballad", topped the R&B chart for nine weeks in September.(A cover version by Aretha Franklin was released in 1968, on the flip side of "See Saw".) 　　Ace began heavy touring, often with Willie Mae "Big Mama" Thornton. In the next two years, he had eight hits in a row, including "Cross My Heart", "Please Forgive Me", "The Clock", "Yes, Baby", "Saving My Love for You" and "Never Let Me Go".In December 1954 he was named the Most Programmed Artist of 1954 according to the results of a national poll of disc jockeys conducted by the U.S. trade weekly Cash Box. 　　Ace's recordings sold very well for those times. Early in 1955, Duke Records announced that three of his 1954 recordings, along with Thornton's "Hound Dog", had sold more than 1,750,000 copies.
