Has the bright sun set,
Has the gale grown stronger?
Still we’ll not grieve yet:
We will sing a while longer!
Has our youth been met
By Time the wronger?
Let us not grieve yet,
Let us sing a while longer!
Is the world beset,
Do the sorrows throng her?
Let us not grieve yet:
Let us sing a while longer!
