With my wife's choir on Friday night we were practicing "Skyfall" by Adele.
It caused an earworm, but the lyrics started warping:

DISCWORLD NIGHTFALL
Nigel Parsons (tune: Skyfall)

This is the Broken Drum.
A place we watchmen like to come.
My brain is turning numb,
Because I'm drinking Scum – ble

This is a friendly pub.
But bring a crossbow, knife or club.
I really should have had more grub.
I'm getting drunk, and here's the rub

When it's night fall,
I drink Scumble.
I would stand tall
If I, If I could stand at all.
At night fall.



There may be more to follow, but I had to get it written down.
Cheers
Nigel
