I didn't know that Vaughan Williams collected Kingsfold to the words of Maria Martin. I assumed he collected it to Dives and Lazarus, as it is incorporated wholesale into his "5 Variations on Dives and Lazarus". I wonder why he didn't call it "5 Variations on Maria Martin"?

I sing Maria Martin. I don't know anyone else who does. (anyone out there?)

The tune fits the lyrics so beautifully.
