The Key to Life on Earth

"The Key to Life on Earth" is a song by the Edish singer Declan McKenna. It represented Eden in the second edition of the Avalon Song Contest.

Background and performance
Talking about the song, McKenna said it "reflects how [he] feel[s] about how hostile human relationships can be and how humans can be towards each other despite how similar they often are". During the live performance, McKenna is joined by the actor Alex Lawther, whom he is often confused with due to having a similar physical appearance. The LED background was use to display iconic locations from the TV Show The End of the F***ing World, which Lawther stars in. McKenna told reporters "the performance sees two people, who are very similar, in conflict with each other, and I think that's the simplest analogy for the song's purpose".
