"Lemon" is the fourth song and second single from U2's 1993 album, Zooropa. Inspired by old video footage of Bono's late mother, the lyrics describe an attempt to preserve memory through film. More than any previous U2 song, "Lemon" showcases Bono's falsetto skills, aided by atmospheric vocals from The Edge and Brian Eno. The song has been described as futuristic German disco. The album version is one of U2's longest songs.
