a very odd question

Is anybody familiar with a musical setting of Gerard Manley Hopkins' "Spring and Fall, to a Young Child"? ("Margaret, are you grieving," etc.) Does one exist?

I found myself singing it while I was washing the dishes this evening, and I am trying to figure out whether I heard it somewhere, or whether I have officially become one of those people who goes around singing poems to tunes of their own invention. The latter would not surprise me at all.
