Casey played with Waller, the bandleader and composer of "Ain't Misbehavin'," from 1930s until Waller's death in 1942. He also played with Louis Armstrong and, after switching to electric guitar, with saxophonist King Curtis and other rhythm and blues musicians.
From 1981 to 2001, Casey was a member of the Harlem Blues and Jazz Band.
St. Peter's Church, at 54th Street and Lexington Avenue in Manhattan, will host a musical memorial service for Casey on September 15. The event was originally intended to celebrate the guitarist's 90th birthday.
