I've just checked with Bill Meek and he's been kind enough to allow me to post here, he's also explained one or two of the more obscure references in the song. Melody is 'What a friend we have in Jesus'

So, 'yer 'tis.

HARRY TATE'S NAVY - Bill Meek.

From the Dogger Bank and Faeroes
From Newfoundland's furthest shore
Rusty weather-beaten trawlers
Came to fight a different war

Changed our fish rooms for a mess deck
Swapped the trawl for sweeping gear
Send out the message on the Aldis
Sleep tight the Harry Tates are here

Through the hell of E-boat alley
Mines and tinfish lurk below
Above the bombs and bullets pound us
No pay no fags nowhere to go

So keep the old 12 pounder firing
Though your plates are almost gone
Through the bloody seas of battle
The Harry Tates are steaming on

Sailing out of Akureyri
To Murmansk on the Russian run
Through the blizzards, fog and ice floes
Through a world that's lost the sun

Shadows always watching o'er us
Junkers waiting for their call
Heinkels and Marchetti Sovoia
The Harry Tates will take it all

Grab your kai and corned beef sarni
While the flying foxes drum
'Cos if the OO should fail us
We're on our way to Kingdom come

By lonely masthead crosses marking
Graves of friends that once we knew
Don't you worry Merchant Navy
The Harry Tates will see you through

When the noise of battle's over
When sanity returns to men
We'll meet you steaming up the Humber
Home to Grimsby Town again

There in Tommy Taylor's madhouse
Where the dockside lasses roam
They'll all be rolling out the barrel
When the Harry Tates come home

Remember England's other navy
When the Harry Tates are gone
