Invitation is a song by Bronisław Kaper with lyrics by Paul Francis Webster, originally used in the film A Life of Her Own (1950). Though it was nominated for a Golden Globe award for Best Score in the original film, it only became a jazz standard after being used as the theme in the 1952 film Invitation. Tony Thomas notes that it was selected for the film for its degree of poignance. It is considered to be Kaper's second best known song after "On Green Dolphin Street." Jazzstandards.com describes it as a "lush and haunting score", and notes that it is most associated with John Coltrane, who recorded.
