Editing Marvin the Paranoid Android (section)

===Marvin's lullaby===
"How I Hate the Night", also known as "Marvin's lullaby", was published in the book ''[[Life, the Universe and Everything]]'', where it is described as "a short dolorous ditty of no tone, or indeed tune." The first verse of "Marvin's Lullaby" appears close to the end of the episode "Fit the Seventeenth", and the second verse soon after the start of "Fit the Eighteenth" as listed below:{{fact|date=December 2023}}

:Now the world has gone to bed
:Darkness won't engulf my head
:I can see by infra-red
:How I hate the night

:Now I lay me down to sleep
:Try to count electric sheep
:Sweet dream wishes you can keep
:How I hate the night

The line "try to count electric sheep" is a reference to [[Philip K. Dick]]'s novel ''[[Do Androids Dream of Electric Sheep?]]'', which inspired the movie ''[[Blade Runner]]''. According to ''Don't Panic'', Douglas Adams wrote a guitar tune for the lullaby, and thought it should have been released.<ref>{{Cite book |last=Gaiman |first=Neil |title=Don't Panic: Douglas Adams and the Hitch-Hiker's Guide To The Galaxy |edition=2nd |year=1993 |publisher=Titan Books |isbn=1-85286-411-7 |page=75}}</ref> In the radio series, Stephen Moore sings the words to a tune resembling "Abendsegen" from [[Engelbert Humperdinck (composer)|Humperdinck]]'s opera ''[[Hansel and Gretel (opera)|Hansel and Gretel]]''.
The song was performed at the very end of the 2012 live radio show.
