DS, signed on the final page by Kurt Weill and Ira Gershwin, two pages on onionskin, 8.5 x 10.25, August 11, 1947. An agreement for the broadcast of the musical Lady in the Dark (with book by Moss Hart, lyrics by Gershwin, and music by Weill), for which the collaborators are to receive a royalty of $750.00. Following brother George’s death in 1937, Ira became involved in projects with a number of other highly regarded composers, including Weill, Jerome Kern, and Aaron Copland. Lady in the Dark opened on Broadway on January 23, 1941, and ran for a respectable 467 performances; a film version starring Ginger Rogers and Ray Milland was released in 1944. Weill is in relatively short supply (and high demand) among twentieth-century composers, and music-related documents, particularly those cosigned by a colleague as distinguished as Gershwin, are of notable scarcity. In fine condition, with trimming to top edges, a touch of mild soiling, and light handling wear. R&R COA.
