It's a reasonable translation (I don't know who did it) of the second verse of Brel's song.
The Adieu Papa verse is pure McKuen.
He also omits the verse dedicated to the wife's lover:
I've never liked the translation with its happy clappy Seasons in the Sun chorus which misses Brel's caustic side.
A possible new chorus might be:
Let them laugh
Let them sing
Let them all dance round and round
Let them dance
Let them sing
As they plant me in the ground.
