William Henry Davies - A Great Time

Sweet Chance, that led my steps abroad,
Beyond the town, where wild flowers grow --
A rainbow and a cuckoo, Lord,
How rich and great the times are now!
Know, all ye sheep
And cows, that keep
On staring that I stand so long
In grass that's wet from heavy rain --
A rainbow and a cuckoo's song
May never come together again;
May never come
This side the tomb.

William Henry Davies
