Melody for my Plungers' Shanty?

Is this post appropriate here? I'm looking for tune suggestions for my Plungers’ Shanty (original content)

 --**--

Our trusty weapons barely dried,

when bilious murky waters rise,

we battle ‘gainst the loathsome tide

And bravely go a’plungin’!

 

No surrender and no mercy paid.

Pungent tides make no parlay.

We’ll see clean water flow today

and bravely go a’plungin’!

 

Heave ho, down ye go!

Heave ho, down ye go!

Heave ho, down ye go!

And bravely go a’plungin’

 

Fearless in the face of horrors,

which roll and breach ‘pon the waters,

and frightened off the last three squatters,

Bravely we go plungin’!

 

Infernal pipes and eddies choked,

To duty we’re forever yoked,

bescumbered, fouled, and fairly soaked.

Still bravely we go plungin’!

 

Heave ho, down ye go!

Heave ho, down ye go!

Heave ho, down ye go!

And bravely go a’plungin’!
