Marshall wrote this song for Shirley Collins, and produced the album on which it was first recorded, Anthems in Eden (1969).  The text Joe gives above is very nearly right; except for:

Verse 1, line 1: "Fifty-onespringtimes"
Verse 2, line 2: "age do allow"
Verse 3, line 2: "or pastures go see"
Verse 4, line 3: "Maypole once was
Verse 5, line 1: "row of straight houses.

Shirley has to be credited with the definitive version; the person who wrote it recorded her singing it.
