From these opening lines, can you name the poem and poet?

You may talk o' gin and beer
When you're quartered safe out 'ere,
An' you're sent to penny-fights an' Aldershot it;
But when it comes to slaughter
You will do your work on water,
An' you'll lick the bloomin' boots of 'im that's got it.
Now in Injia's sunny clime,
Where I used to spend my time
A-servin' of 'Er Majesty the Queen,
Of all them blackfaced crew
The finest man I knew

Eudyard Kipling "Gunga din"

Though I've belted you and flayed you,
By the livin' Gawd that made you,
You're a better man than I am, Gunga Din!

"Now in India's sunny clime,
Where I used to spend my time,
A' servin' of Her Majesty The Queen,
Of all that black-faced crew,
The best I ever knew
Was our regimental bhisti,
Gunga Din." - Rudyard Kipling

Didn't it happen at Khyber Pass
Where Gunga Din breath'd his last?
Still a dangerous place to be,
But why the re-make, Sergeants Three?
Well enough they should have left alone,
The better movie, better known,
Sam Jaffe was a better
Gunga Din. - DorianGreyed
