A tip for those looking for the author on a search engine: it's "Kavanagh" without the "u."
"His celebrity as a dancer was very much intertwined with his celebrity as a larger than life character and blatantly sexual being."
Really did the whole world know about his sexuality? I think not.
Many of his fans were women(so were Fonteyn's) and in the 60's people who went to the ballet in London where he spent a lot of time, were publicly less obsessed with sex and his appeal to gay men at that time seemed very limited.
In the UK in the 1960's at least, the population was only just leaving behind the accepted moral code of the earlier majority. Nureyev's sexuality was not discussed in the press and it was only when his partner, assistant and film maker was seen regularly around, that any such talk really developed among ballet goers. He was frequently photographed with women and there was gossip about him and a member of America's high society and others.
His earlier relationship with Erik Bruhn was known, that was seen to have an aura of romance about it. It was not discussed in sordid or explicit terms in my experience and never reached the press at that time.
Having watched ballet in various countries since 1960 when still at school, it was my impression that ballet-goers were more interested in performances and what was happening next season rather than cheap gossip.
It is quite apparent to everyone that society values have deteriorated and people are now baying for the blood and souls of distinguished people of culture, who made inestimable contributions to many lives.
I think Kavanagh's book on Ashton missed elements of his personality that I had witnessed and that senior members of the Royal Ballet were affronted at much which was said in her biography.
