Daisy Bell

"Daisy Bell" was a song performed at the Palace Theatre in 1889 whilst the Fourth Doctor and Leela were attending. The performer sang the lines:


 * Daisy, Daisy, give me your answer, do. 
 * I'm half crazy all for the love of you. 
 * It won't be a stylish marriage. 
 * I can't afford a carriage. 
 * But you'll look sweet on the seat of a bicycle build for two.

The audience joined in with the chorus. The Doctor assured Leela that they were not obliged to do the same. (TV: The Talons of Weng-Chiang) In 2367, Robots 1 and 2 sang this song when the Eleventh Doctor deactivated them. (TV: Dinosaurs on a Spaceship)

Behind the scenes
The robots singing "Daisy Bell" as they died is a reference to HAL doing the same in Arthur C. Clarke's film, which was itself a reference to the first song ever sung by a computer made by a human (the IBM 704) in 1961.
