"Can't Get Out of This Mood" is a popular song composed by Jimmy McHugh with lyrics by Frank Loesser, written in 1942 for the RKO film Seven Days' Leave. It was one of six songs the pair contributed to the picture, alongside numbers like "A Touch of Texas" and "I Get the Neck of the Chicken." By the time of this collaboration, McHugh had already established himself as one of the most prolific composers of the era, with over 500 songs to his credit, including enduring standards written with Dorothy Fields such as "I Can't Give You Anything But Love" (1928), "On the Sunny Side of the Street" (1930), and "I'm in the Mood for Love" (1935). His partnership with Loesser in the early 1940s represented a distinct creative period between his celebrated work with Fields and his later collaborations with Harold Adamson. Johnny Long and His Orchestra made the first recording in 1942, and Frank Sinatra recorded it for Columbia Records that same year, helping to establish the song's presence in the wartime popular music landscape. Kay Kyser also contributed a notable version. Sarah Vaughan later became closely associated with the tune, lending it renewed jazz credibility. While it never reached the canonical status of McHugh's best-known compositions, the song has maintained a quiet presence in the repertoire, attracting singers drawn to its evocative title and melodic appeal.
