Though I don't know how much credit I can take . . .

You should certainly take some. The work strikes me as very much a collaboration, just as a setting of a poem as song lyrics doesn't minimise the poet's contribution, if that makes any sense.

Imagine what the piece would be like if the visual aspects were just the same, but the text were: "There are fairies at the bottom of our garden/They often like to dance on summer nights..." ;-)
