Handwritten musical manuscript in pencil by Duke Ellington, unsigned, one page both sides, 9.5 x 12.5, headed, "(at Club)—Right to Sing Blues." Ellington transcribes passages of this jazz and blues standard, originally composed as 'I Gotta Right to Sing the Blues' by Harold Arlen in 1932, to be played by his band members Harry Carney (baritone saxophone), Lawrence Brown (trombone), and Cootie Williams (trumpet), noting "ad lib" for solos at the end. In very good to fine condition, with intersecting folds, edge creasing, and overall light brushing to the pencil. Most of Ellington's scores are housed in the Smithsonian Institution, making any page in private hands quite scarce.
