That's Amore was performed by Dean Martin for the 1953 film The Caddy, with music by Harry Warren and lyrics by Jack Brooks, and it quickly became one of Martin's signature songs. Its playful lyrics about love in Naples and its instantly hummable melody helped it endure long after the film, appearing in later movies, adverts and nostalgic playlists. In recent years the opening has been clipped for memes and short videos, where its old-fashioned romance is used ironically or affectionately over everyday moments, keeping the song familiar to new audiences.
