You could be right, granama1 - but my memory gets wiped after a month or so!
I think the wordplay for 1ac is -
synonym for 'siren'/temptress (for the V word) synonym for 'throw in' (for the short A word) + synonym for 'rope' - a Scots word ('tarry-breeks' is Rabbie Burns' sailor) which together give a synonym for 'going off'.
