"- What are you singing?
- Là ci darem with J. C. Doyle, she said, and Love's Old Sweet Song." ([U4.313])

La ci darem la Mano (in Italian = there we will be holding hands) is a duet for the characters Don Giovanni (baritone) and Zerlina (soprano) in Mozart's 1787 opera Don Giovanni (act 1, scene 9). In this aria, Don Giovanni is trying to seduce the peasant girl Zerlina on the day of her wedding to Masetto.

Love’s Old Sweet Song is a Victorian parlour song published in 1884 by composer James Lynam Molloy and lyricist G. Clifton Bingham. It is sometimes referred to by the title "Just a Song at Twilight," the first line of the chorus.
