Suddenly It's Spring is a song written by Jimmy Van Heusen (music) and Johnny Burke (lyrics). It was copyrighted in December 1943 and published that year. It was tied to the 1944 film Lady in the Dark, where Ginger Rogers with Don Loper performed it; the number was cut from the film but a recording was released and promoted with sheet music connected to the movie. The first theatrical release date is February 9, 1944. The tune has since become a jazz standard and is often performed as a Great American Songbook piece, with vocal takes by Hildegarde, Ginny Simms, Glen Gray and His Casa Loma Orchestra, and instrumental versions by Stan Getz in 1955 and Zoot Sims in 1983. It remains associated with the Lady in the Dark soundtrack and is widely covered in both vocal and instrumental jazz contexts.
