Ms Morris, with whom Prince Philip used to go dancing at the Cafe Royal in London in the late 1930s, died aged 99 on October 28. The pair met as World War 2 was beginning, when Ms Morris moved back to the UK after having studied and performed in Germany.
The singer was based in a splendid home in Groom Place, Belgravia, where she hosted several parties for socialites.
Among them, there was Osla Benning, the Canadian god-daughter of Lord Louis Mountbatten and first serious girlfriend of Prince Philip.
With time, the singer also became one of the future-Duke’s confidants, providing an ear for his troubles.
Speaking about the Duke, Ms Morris said, according to the Daily Telegraph: “He had a black bear on his shoulder.”
Ms Morris would meet Prince Philip’s wife the Queen years after the war ended and his relationship with Ms Benning was a thing of the past.
The singer performed for the Queen at a Royal Variety Performance in the 1950s.
Two decades earlier, Ms Morris had also sang in front of Adolf Hitler at the Bayreuth Festival.

Ms Morris was raised in Northumberland but sent to Dresden in her youth to study the violin and train as an opera singer.
There, she lives a tranquil life until November 1938, when SA paramilitary forces ransacked and demolished Jewish shops and building and arrested more than 30,000 people.
Ms Morris returned to the UK on the eve of the war and, in London, she was offered to work as a German translator for the intelligence services.
