Bionie and the Robotics

From the song "Bionie and the Robotics" by Ray Stevens from his 1986 album Surely You Joust.

Vocal quartet formed of four artificial intelligences:

They met by chance at the computer repair.
While in for update on their basic software.
They came from different sectors of computer society
but when they got together it was instant harmony.
One was the voice on an Otis elevator.
One was a telephone information operator.
One was a NASA assistant data integrator
and one was a Toyota dashboard warning indicator.

They sing in 1950s Doo-wop style.
