Hi Nhaus, I also can't parse 9d; I just guessed it from the two names. Can anyone else explain??
5d; the first two letters are the usual abbreviation for 'about' and the rest is the word for describing the position of the foetus.
COD was 6d which made me laugh out loud, but also a shout-out for 23a which I thought was one of the best first-letters clues I've seen. Also really enjoyed the spoonerism.
