The song was inspired by a 2018 Christmas holiday trip to
St. Lucia by Ezra and his friends. About the lyrical background of the song, Ezra explained, "there was a street party going on, with three different sound systems, people cooking in the street. I asked a woman what was going on and she told me it was a funeral – for three people. They were celebrating three lives! I thought: that is not how we do this at home. And it's really beautiful". The song release coincided with an announcement of his 2022 UK Arena Tour. He performed the song, as well as a cover of
Mimi Webb's
House on Fire which was released on 18 February, during a BBC Radio 1 Live Lounge performance on 19 May. "Green Green Grass" is composed in the key of
A major with a
tempo of 113 beats per minute, with Ezra's vocals ranging from A5 to E4. Ezra performed the song during the
Platinum Jubilee Central Weekend in June 2022. The singer revealed that he was asked to omit the line "on the day that I die" from the performance beforehand. ==Music video==
