It's A Blue World is a jazz standard written by George Forrest and Robert Wright for MGM. It was first recorded by Glenn Miller and His Orchestra with Ray Eberle, with the recording made on December 6, 1939 and released December 22, 1939. The song expresses a melancholy view of a world that is blue without a beloved person. It reached the stage in Tony Martin’s 1940 theatrical release, and over the years has been covered many times in vocal and instrumental versions. Notable versions include The Four Freshmen on their 1949 album It's A Blue World and a 1952 release, Frank Sinatra in 1962, and Ella Fitzgerald with Nelson Riddle in 1962. The tune remains a staple of big band and vocal jazz repertoires and showcases the Wright and Forrest collaboration, known for adapting classical material for popular musical theatre.
