"We go walking on the green grass" is actually the first line of the song Sailor-Boy in the collection. It's from Sharp's English Folk Songs from the Southern Appalachians (this is the antepenultimate song No.272 version B, the general title being Soldier Boy For Me), so not strictly English (or British even), (Roud 1302 seems, at a quick look, to have been collected only in the US).

The accompaniment for this is mostly single line dotted rhythm, except for a chorus section added by Britten, where a few chords appear. It is one of my favourite accompaniments though, and not the most startling (that would be Bonny At Morn, IMHO).
