The chords (key: D) given in Clancy & Makem's The Irish Songbook (Oak) are:

Look at the [D]coffin, with [G]golden handles.
Isn't it [D]grand, boys, to be [E7]bloody well [A7]dead?
Let's not have a [D]sniffle; [G]let's have a bloody good [D]cry
And [G]always remember; the [D]longer you live,
The [Em7]sooner you'll [A7]bloody well [D]die.
