Coldplay frontman Chris Martin revealed to the Wall Street Journal that Paltrow would be featured on the song "Everglow," despite their recent divorce. The song is described as being "about a relationship's enduring spark."
"Everyone who got asked to sing on our album has an important part in our lives. This is the Wall Street Journal, so I don't want to get too hippie, but what I'm trying to learn in my life is the value of every human," Martin said. "Inclusiveness is the key thing, and it all comes from that 'Guest House' poem. The 'choir' started with my two kids coming in after school and recording. We recorded Blue Ivy Carter in New York when her mom Beyoncé was in the studio. It comes from learning about Greek tragedy, where the chorus chimes in at times. To me, when we use that sound, it's to affirm what I'm saying. 'We agree with you, Chris. Keep singing.'"
The singer said a 13th century poem by Rumi inspired the collaborations, with also include songs with Beyonce herself, Noel Gallagher, Tove Lo, Martin and Paltrow's children and Martin's current girlfriend Annabelle Wallis.
