Sir Elton John praised Bowie for dealing with his cancer battle with dignity.

He said: “What I loved about him towards the end was his incredible privacy during what must have been 10 years of incredible bad luck with illnesses, heart attacks, cancer, whatever.

“He kept it private in an age we’re living in with Twitter when everyone knows everything about everything – he kept it to himself.

“He made two albums without anybody knowing he was making them. He had treatment for his illnesses without anyone knowing or anyone saying anything.

“And that is the mystique of the man, because we know David Bowie the figure, the singer, the outrageous performer, but actually, we don’t know anything about him – and that’s the way it should be in music and should be in any art form whatsoever.”
