Ok: it's taken a while longer than I thought, and I still can't quite make out the third line in the second verse, but perhaps one of you who knows it from before can supply the missing words or corrections? I have put in caps the dubious bits.
And I hope our 2 guests, Grainne and Hope are still tuning in: why don't you become full members, then I could have pm-ed you the words?

THE DISMISSAL
As a husband you are neither bad nor good,
but you please me not - with your foolish show,
With your huff and puff in your iron suit
You're as heavy as a gross of cannonball
Only good for battering down a wall
And you don't know what you're at, at all, at all
And this marriage is no longer convenient.

I have seldom seen a poorer manner in a boat,
Besides you're the heaviest brazen load,
When the ship STANDS ? you've a pea-brained WAVE? BRAVE?
As the captain's mate you don't know your place,
You can't handle reefs nor oars nor steer,
You're of no use to neither man nor beast,
And this marriage is no longer convenient.

I have seldom seen a poorer figure at the dance,
You have two left feet,
You've done the reel for the jig
And the jig for a reel, how you shake the floor,
For an armed man, you have no amour,
I would never be enamoured of life no more,
You're no more a husband than I a wife,
And this marriage is no longer convenient.

As it goes into the instrumental after it, she shouts something, perhaps "I'll not save you"?
