Too much turkey is maybe fogging the brain, but I can't get anywhere with the three normal clues. I infer something seasonal and wait-y, but (despite having performed hundreds of these) I can't see wood for trees. Also having a problem with the letters in (c) which make no sense, so probably something wrong there as well. The parsing of 31 eludes me, though I'm pretty sure I know who he is. Off to the piano for aural help, I think.
