No boxing gloves or morning trains in the original song, only in the later parodies. Here's how I sing the vanilla convict version.

TEN THOUSAND MILES AWAY

Sing ho! for a bold and a gallant ship,
And a fast and favouring breeze,
A bully crew and skipper too,
To carry me o'er the seas;
To carry me o'er the seas, my boys,
To my true love far away,
For I'm taking a trip on a Government ship
Ten thousand miles away.

CHORUS: Then blow, ye winds hi-ho!
A-roving I will go.
I'll stay no more on England's shore
To hear the music play
I'm off on the morning tide
Across the ocean wide
I'm taking a trip on a Government ship
Ten thousand miles away.

Oh, dark and dismal was the day,
When last I saw my Meg
She'd a Government band around each hand
And another one round her leg
And another one round her leg, my boys
As the big ship left the bay,
"Adieu," said she, "remember me,
Ten thousand miles away!"

My true love she was beautiful,
My true love she was young,
Her eyes they shone like diamonds bright
And silvery was her tongue
And silvery was her tongue, my boys
But now she's far away
For she's taken a trip on a Government ship
Ten thousand miles away!

I wish I was a bosun bold
Or even a bombardier
I'd build me a boat and away I'd float
And straight for my true love steer;
And straight for my true love steer, my boys
Where the dancing dolphins play,
Where the whales and the sharks are having their larks
Ten thousand miles away.

Oh, the sun may shine through the London fog
And the Thames run fine and clear,
Or the ocean brine be turned to wine
If ever I forget my dear
If ever I forget my dear, my boys
Or the landlord's quarter-day
If ever I forget my own true love
Ten thousand miles away.
