It was in 1961 that IBM programmed a computer to sing for the first time. The computer was a UNIVAC and the tune was the cute 1892 ditty, “Daisy Bell.” It was in 1968 that HAL, the computer in 2001: A Space Odyssey crooned the same song in a creepy, sickly voice. The full lyrics, if you’d like to sing along:

“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 upon the seat of a bicycle built for two”
