Sir David Attenborough made a surprise appearance at the 2019 Glastonbury Festival.
The famous wildlife presenter took to the main Pyramid stage to launch a brand new BBC Natural History series called Seven Worlds, One Planet.
They showed a four-minute trailer for the series on the big screens to a crowd of over 100,000 people.
The show features a music collaboration from singer Sia and legendary music composer Hans Zimmer on an original song called Out There.
Makers of the show said: "Each one-hour episode will transport viewers to a single continent and tell the story of its spectacular wildlife and iconic landscapes".
They also said they'll be using new and exciting camera techniques to bring the audience even closer to the wildlife.
Sir David Attenborough also thanked festival-goers for cutting their plastic use.
