Live 1972 cover of the Donovan song, based on a poem  by Christopher Logue.

Be not too hard for life is short
And nothing is given to man
Be not too hard when he is sold or bought
For he must manage as best he can
Be not too hard when he blindly dies
Fighting for things he does not own
Be not too hard when he tells lies
Or if his heart is sometimes like a stone
Be not too hard for soon he’ll die
Often no wiser than he began
Be not too hard for life is short
And nothing is given to man
