A short, wistful verse about Robin Hood in the greenwood and Little John away in town. It reads more like a snatch of old ballad than a nursery rhyme, which is exactly what it is.
From Mother Goose / Nursery Rhymes (traditional). See the whole collection.
Robin Hood, Robin Hood,
Is in the mickle wood!
Little John, Little John,
He to the town is gone.
Robin Hood, Robin Hood,
Telling his beads,
All in the greenwood
Among the green weeds.
Little John, Little John,
If he comes no more,
Robin Hood, Robin Hood,
We shall fret full sore!
