Young at Heart was composed by Johnny Richards with lyrics by Carolyn Leigh in 1953. The tune originated as an instrumental piece by Richards titled Moonbeam, to which Leigh added her lyrics. It was first recorded by Frank Sinatra with an orchestra conducted by Axel Stordahl, released as a single on Capitol Records in late 1953, where it became a million-selling hit reaching number two on the Billboard chart. The composition is a gentle, sentimental pop ballad with a flowing melody and warm harmonic support, conveying an optimistic outlook on love and life. Its commercial success was so significant that a 1954 Doris Day and Sinatra film was retitled Young at Heart to capitalize on the song's popularity, featuring it in the opening and closing credits. Richards himself was primarily known as a bold jazz arranger who created ambitious works for Stan Kenton's orchestra, including Cuban Fire and an adaptation of West Side Story, making this tender pop standard something of an outlier in his catalog. The tune has been widely covered across pop and light jazz settings by artists including Jimmy Durante and many others, maintaining its place as an enduring standard in the Great American Songbook.
