Someone suggested Nadia was at the celebrations after Cleo Laine was made a Dame by the Queen.   I doubt that somehow, unless there has been apologies all round.   Ms Cattouse cited Cleo as Co-Respondent in her divorce from Dave Lindup and only withdrew the allegation (which was false) at the eleventh hour.   There was quite a scandal about this in the British newspapers at the time...early 60's I think.
As far as I remember Nadia's popularity quickly faded after that.
