Also known as: デイジー・ベル, 二人乗りの自転車, デイジー・デイジー
"Daisy Bell (Bicycle Built for Two)" is a popular song with the well-known chorus "Daisy, Daisy / Give me your answer, do. / I'm half crazy / all for the love of you", ending with the words "a bicycle built for two".
Notably, it was the first song sung by computer speech synthesis in 1961, and is accordingly often used by AI characters in fiction, from HAL 9000 to Caine (The Amazing Digital Circus).
