Not a lot of golden stuff this week even though there was a pleasant semi-theme. Anyways, here goes:
1 down: (Beatles) 17-down’s own crab & kipper stew — just add water (9, 6)
Nice little anagrammer: crab & kipper stew — just add water = paperb ck ri + awter = Paperback Writer = Beatles’s own.
19 across: Indirectly he may conceive two hairstyles, no, in shabbier extremes (5, 5)
Nice direct definition: two hairstyles, no, in shabbier extremes = perm do no in sr = sperm donor = indirectly he may conceive.
4 down: The French contacted diminutive singer, live, for 17-down’s own (3, 2, 2)
Interesting little word in there: the French contacted diminutive singer, live = le tit be = Let It Be = Beatles’s own.
I don’t quite get diminutive singer = tit, though.
