Ref:parody of 'Down below' it reminded me of a similar song [sorry Ross, but until I read the RN version I'd clean forgot this].

At the bottom of the hull             Ch. Down below
That's where you'll find the bilge   Ch. Down below
Full of rubbish, full of grime
Full of sludge, and full of grime
Full of shit, O never mind!          Ch. Down below

There's cockroached galore
There dead rats by the score
There's things that have been seen
Far worse than your worse dreams
The thought 'ud make you scream.

When the bilges overflow
It's down there you must go
The apprentice was sent down
Then we heard a dreadful sound
And not a trace was found.

But sometimes you will hear
A tale to make you cheer
How on the 'Clan MsGill
They found a gold bar down the bilge
So there's hope for us still .
