"Lilly" is a 1975 Italian song composed and performed by Antonello Venditti, lead single of the eponymous album.
The song tells the story of a friend of Venditti from Milan who died of a heroin overdose. At the time of its release, it raised several controversities because of the crudeness of the lyrics. The song proved to be a surprise hit, definitively launching Venditti's career. In spite of being one of Venditti's major hits, Venditti rarely performs the song live, and only in Milan.
