"Skylark" is an American popular song with lyrics by Johnny Mercer and music by Hoagy Carmichael, published in 1941. Carmichael wrote the melody, based on a Bix Beiderbecke cornet improvisation, as "Bix Licks," for a project to turn the novel Young Man With a Horn into a Broadway musical. After that project failed, Carmichael brought in Johnny Mercer to write lyrics for the song. Mercer said that he struggled for a year after he got the music from Carmichael before he could get the lyrics right. Mercer recalled that Carmichael initially called him several times about the lyrics but had forgotten about the song by the time Mercer finally wrote them. The yearning expressed in the lyrics was based on Mercer's longing for Judy Garland, with whom he had an affair.
This song is considered a jazz standard. Additionally, it is believed to have inspired a long-running Buick car of the same name that was produced from 1953 to 1998.
