This one was unusually easy, but nevertheless I'm bewildered by a few of the clues.
14a: Craft this tune? Croat folk dancing (4) The answer is obvious, but I don't get "craft this tune".
26a: The old quit part in play, a part requiring backflip (4) This is the only one I'm not sure about. I have APA_ and assume that it's APAY, but can quit mean the same as requite?
19d: Isopteran, half to take note of, millions disposed of (7) Again, the answer is obvious, but I'm experiencing a brain-freeze.
