Check on 22a - I am presuming that it is Berka here - (Fool about in islamic dress). I am used to spelling it Burqa but then a lot of Arabic is phonetic when translated.
Also 1a Chicken and fish having been inside cooked sent back (6) C---r-
This will tee up 2d Crew is tossed around ocean - they are not as clever as they think (9) ----a-r-s
Finally 8d I am believe is Notables? (Bar with standing-room only)?
Chambers gives the fool as berk or burk and the Islamic dress as burka, burkha or burqa. The two that together can satisfy the clue are BURK and BURKA.
