[Derek] Shackleton was a man who - it's probably arrogant to say it - but he was a little bit like me. He undertook incredible dangers and carried on over the sea and over the ice and all the rest of it. He was a remarkable man.

I've often thought about that and the only suitable member to join me on that climb [to Everest] was George Lowe: he was strong, a good man on a mountain, with a great sense of humour, and I liked that. I think George and I could've done that together ... I've probably never told George that.

On the summit of Everest, I had a feeling of great satisfaction to be first there.

Many people have been getting too casual about climbing Everest. I forecast a disaster many times.

I think my strengths perhaps are that I'm determined. I may not be the best climber in the world, but I do like to sort of succeed and so that tends to drive me on, as it were, and I don't give up too easily.

I was incredibly stubborn. I mean, I believe that my father was frequently in the right, but I would never admit it, and so we did have a few set-tos on various topics; but on the whole as I got older and my father got more mature we got along reasonably well.

I'm definitely a Queen supporter. She was great.
