Shakespeare - still quite good

This evening I finished reading Chance Witness, the memoirs of Matthew Parris, which is the most page turning political/media memoir I've ever encountered.
The prologue to the final chapter is a quote from Henry V which I don't remember reading before:
"A good leg will fall, a straight back will stoop. a black beard will turn white, a curled pate will grow bald, a fair face will wither, a full eye will wax hollow, but a good heart, Kate, is the sun and the moon: or rather, the sun and not the moon; for it shines bright, and never changes, but keeps his course truly."
Put the name "Kate" in any sentence and somehow it sings. And, to be fair, that's a bit more than a sentence.
