This is a parody of the Bee Gees' 'night fever'

With his sanity, such that it is, beginning to slip with all the singing, Abaddon tries to relax by searching for stragglers in an abandoned Imperil city. After about an hour of searching he decided to clime to the top of the tallest building left standing to get a better view when he hears music beginning to play. Below a squad of Night Lords led by a Chaos Lord are taping their feet, "noooo" Abaddon groaned.

Chaos Lord: Listen to the ground:

There is movement all around

There is something goin' down

And you can't stop it

Chaos Lord: On the waves of the warp,

There are Daemons out there

If it's stoking your soul

And it will eat it

Chaos Lord: And that dreaded Chaos Marine,

He moves through the night,

Crushing your mind and your soul

When you watch out for me

Yeah, and there's no light

Chaos Lord: Then you get the night fear, night fear

We know how to do it

We give ya that night fear, night fear

We know how to bestow it

Chaos Lord: There you are,

Prayin' for this madness to end,

Your soul on the line,

Blowing in the wind,

I'll make it mine.

Chaos Lord: Night fear, night fear

We know how to do it

We give ya that night fear, night fear

We know how to bestow it

Chaos Lord: In the cold of the night,

Don't need no help, your soul we will take it

Give up you'll never make it to morning

I got Daemons in my mind

I got higher in my stalking

And I'm gloating in the dark;

I give no warning

Chaos Lord: And that dreaded Chaos Marine,

He moves through the night,

Crushing your mind and your soul

When you watch out for me

Yeah, and there's no light

Chaos Lord: Then you get that night fear, night fear

We know how to do it

We give ya that night fear, night fear

We know how to bestow it

Chaos Lord: There you are,

Prayin' for this madness to end,

Your soul on the line,

Blowing in the wind,

I'll make it mine

Chaos Lord: Night fear, night fear

We know how to do it

We give ya that night fear night fear

We know how to bestow it

As the few stragglers fled the city, the Night Lords celebrated the success of their clean out mission, unaware that Abaddon was bashing his head repeatedly against a section of wall high above them.
