2 clues that could have 2 solutions: 9d Further attempt to clear up that's over (4) Last letter could be D or O. 22a Unattractive expression one pulled (4) First letter could be G or P. And 29a Those working in capitals maybe give power to muscle? About right. (9) Can't understand the parsing. Obviously too much sloe gin over Christmas!
9d. I have O (two part construction)
22a. I have G (seven letter word for expression minus last three letters)
29a. Three letters “give power to”, then a five letter “muscle” (in the shoulder) around one letter “right”
