"The Revel", said to have been sung by Irish soldiers dying of cholera in India in the 18th century. Versions appear in the database under the titles "Here's to the Last to Die" & "We Loop in the Purple Twilight".

We meet neath the sounding rafter,
And the walls around us are bare,
And the dead echo back our laughter,
For they know that we'll soon be there.

Then stand to your glasses steady.
This world is a world of lies.
Here's a sip to the dead already,
And a cup to the next that dies.
