And the thrushes and the finches make scarcely a tune.

CHORUS: Oh, when will this winter be over? When will this winter be done?
When the Green Man walks the forest, then we'll know spring's begun.
When the Green Man comes a-walking, then we'll know; then we'll know.

On the bushes and hedges not one leaf on show,

He curses the weather and loudly he calls:
