Here is a small submission:

A Team is foolish enough to get all three of Golgarach's questions wrong, making a mess of their quest, and forcing the wall monster make good on his promise to feed on the Dungeoneer. As he is about to do so, the entire cast of Knightmare appears, standing in a line, and sings:

'Feed the wall

Let him know it's quest mess time

Feed the wall

Let him know it's quest mess time...'

Well, it's time for the full version   - a charity song by the Knightmare cast, for the starving wall monsters of Series 3, who never got any dungeoneers to eat. The song is a hope that, when a dungeoneer messes up their quest, at that time they will be fed to the walls. (Sorry, Sir Geldof!) Original song and video {here}.

[Motley:]

It's quest mess time

There's a need to be afraid

At quest mess time

We're punished for mistakes we made

[Mogdred:]

And in our Dungeon nightmare

We can't spread a smile of joy

Throw your arms up in the air

At quest mess time

[Mrs. Grimwold:]

But say a prayer

Pray for the other walls

At quest mess time it's hard

[Hordriss:]

But when you're having food

There's a wall inside the Dungeon

[Merlin:] And it's a wall of dread and fear

Where the only water flowing is

[Treguard joins in:]

The sweat of dungeoneers

And the time-out bells that are ringing

Are clanging chimes of doom

[Treguard only:] Well, tonight thank God it's them instead of you.

[Everyone:]

And there won't be food for Brangwen Shee this quest mess time.

The greatest gift she'll get this year is graffiti

Where nothing ever grows

No human-flesh-to-go

Do they know it's quest mess time at all?

Feed the walls

Let them know it's quest mess time

Feed the walls

Do they know it's quest mess time at all?

[Motley:]

Here's to you

raise a Helm for everyone

Here's to them

Starving up on Level One

Do they know it's quest mess time at all?

[Everyone:]

Feed the walls

Feed the walls

Feed the walls

Let them know it's quest mess time again

Feed the walls

Let them know it's quest mess time again

Feed the walls

Let them know it's quest mess time again...
