Lyrically, the song's theme revolves around the singer's confession of his unfaithfulness to his lover and, now that she's gone, his realization of his foolishness.
What was most attractive in the young singer's performances was her musical and verbal expressiveness, her wholehearted involvement in lyrical content of a piece.
The song concludes with the piano accompaniment, despite the histrionic singer's pleas, becoming uncontrollably fast, and the singer having to escape the studio.
