"I am looped in the loops of her hair"

For the past couple of days I have been somewhat swallowed up in Eva Ibbotson's The Morning Gift. This was the one Ibbotson historical I'd somehow missed. I'm going to finish it tonight, so a review will be forthcoming. But until then, please have this—Christopher Plummer's unparalleled recitation of "Brown Penny" by W.B. Yeats. A line from this poem makes a brief but shatteringly perfect appearance in The Morning Gift, and I can't . . . I can't get it out of my head.
