F1 champions at Bahrain - slideshow

The organisers of the Bahrain Grand Prix brought out 17 of the 19 living F1 world champions to the season opener last weekend.

Some of them took part in a parade in their championship winning cars or in other cars which were laid on for them to drive.

On Sunday morning I went down to the tent behind the paddock to see the drivers getting into their cars before the parade. It was incredible.

Here were the cars and drivers I had grown up watching. I have worked with and got to know quite a few of them, like Emerson Fittipaldi, Mario Andretti, Jody Scheckter and Jackie Stewart in particular, but had never had the chance to see them in their original cars and certainly not together.

Seeing Jackie's car, lined up behind Emerson's, both drivers sitting in the cockpit with umbrellas sheltering them from the sun, was like being back in the early 1970s.

An astonishing experience.

It was like being on a movie set. These photos don't really do it justice, but I wanted to share them with you anyway.
