Attenborough at Glastonbury event

Sir David Attenborough has made a surprise appearance on Glastonbury’s Pyramid stage to launch the BBC’S new natural history series Seven Worlds, One Planet.

The broadcaster and naturalist introduced a fourminute prequel video to the huge crowds gathered ahead of Kylie Minogue’s performance at the festival, being held on Worthy Farm.

The extended trailer features a new song, Out There, from Australian singer Sia who has collaborated with composer Hans Zimmer on the track.

The 93-year-old told the audience they had been listening to the sounds of ocean creatures featured on Blue Planet II.

“There was one sequence in Blue Planet II which everyone seems to remember,” Sir David said. “It is one in which we showed what plastic has done to the creatures that live in the ocean. It had an extraordinary effect and now this great festival has gone plastic-free.”

Kayleigh Townsend, from Yorkshire, said seeing Sir David on the Pyramid stage was “inspiring”. “To give him the main stage and make sure as many people heard him as possible was great,” she said.
