Paramedics from Greater Manchester Ambulance Service took him to Manchester Royal Infirmary, where he was pronounced dead.  

A spokesman for Greater Manchester Police said there were no suspicious circumstances surrounding the death of Mr Crisp, who had been living in New York since the 1980s.  

He had been due to appear at a The Green Room in Manchester on Monday in a one-man show which was supposed to then move on to Liverpool, Brighton, Leeds, Birmingham and London's West End.  

A stage play about his life, Resident Alien starring drag queen Bette Bourne, is coincidentally due to open at London's Bush Theatre.  

Christopher Hodson, press manager for The Green Room, said everyone involved in the production was dismayed to hear of his death. "It is very sad to hear of his death and we hope to do something to sensitively mark it, but we have only just heard the news," Mr Hodson said. "It is very poignant."  

However, Patrick Newley, Crisp's close friend and press agent for most of the 1980s, said he would still be alive if he had not undertaken the tour. Crisp, who would have been 91 on Christmas Day, had been reluctant to do it but was incapable of saying no, said Mr Newley.  

"I am very sorry indeed to hear of his death and sadly shocked because when I spoke to Quentin roughly two or three weeks ago in New York he was clearly not happy about coming over for the tour," he said. 

Quentin was cremated on Thursday 25th November in Manchester. His ashes will be flown home to New York. I understand that, in accordance with his wishes, there will not be a funeral.  
A memorial service will be held in New York in a few weeks time.
