Attenborough, 94, will be laying down a tasty beat on Dave's new single, titled 'Dave Times Two'. OK that's not true, it's Dave the rapper who will be making a foray into Attenborough territory for a Planet Earth special.
Planet Earth: A Celebration has been billed as 'the ultimate natural history thrill ride' and will be comprised of eight of the very best sequences from the Bafta award-winning Planet Earth II and Blue Planet II.
For the special, 'designed to lift viewers' spirits during a time of international uncertainty', Attenborough has recorded a new narration, while composer Hans Zimmer has created new compositions and rearranged the original scores.
Dave performed grand piano on the new recording, alongside the BBC Concert Orchestra on strings, with the whole thing filmed at the Lyndhurst Hall at Air Studios, London.
Brit Award-winner Dave, 22, said: "I've always been a fan of powerful natural history documentaries. This is a programme where nature and music come together, so it was only right that I lent my talent, my time, and my attention to this project.
"It was a pleasure to work alongside Sir David Attenborough and Hans Zimmer."
Zimmer, known for his work on films such as The Dark Knight, Gladiator, and The Lion King, said: "Working with David on so many of his magnificent programs celebrating nature and our planet has been a joy for me. I am constantly inspired by what he is able to capture, and the collection of sequences featured in Planet Earth: A Celebration is truly special."
So we've got amazing animals, a sensational score and two Daves? What's not to love?
Indeed, BBC Director-General Tony Hall doesn't really sound like he's over-egging it in describing this special as a 'spectacular treat'.
He said: "The BBC has curated this amazing collection of sequences from two of the most talked about natural history series of recent years, Planet Earth II and Blue Planet II, as a spectacular treat for the viewers.
"With brand new narration from the brilliant David Attenborough, a new score from Hans Zimmer and the team at Bleeding Fingers played by the BBC Concert Orchestra with Dave on the piano, this thrilling journey around the world promises to lift everyone's spirits."
Planet Earth: A Celebration doesn't have an exact air date yet, but it's expected to be broadcast on BBC One at the end of the month.
