Famous quotes containing the word greenwood:
“Oh, many a day have I made good ale in the glen,
That came not of stream, or malt, like the brewing of men;
My bed was the ground, my roof the greenwood above,
And the wealth that I sought, one far kind glance from my love.”
—Unknown. The Outlaw of Loch Lene (l. 1–4)
