This track had to be rush-recorded in a motel room in El Paso, Texas. "It was like a 115°F [46°C] outside so we had to turn the air conditioning off so we could actually record the microphones, and it just got unbelievably hot," the band's Iain Cook told BBC's Newsbeat.
"Maybe that was helpful though, to enhance our performance," singer Lauren Mayberry added.
Mayberry told Coup De Main magazine this is her favorite track on The Bones of What You Believe. She explained: "It was the last, last one we finished to go on the record - we didn't know if it was going to make it or if we were going to save it for something else. I think it probably represents for me where the band is at best, the sounds and the lyrics and the production feels to me, the most Chvrches song on it. It's got a nice bitter sweetness to it, which I think sums up where we're at."
"Pink Cadillac" was a B-side for Bruce Springsteen in 1984, but after Aretha Franklin sang about pink Cadillacs on "Freeway Of Love" the following year, Natalie Cole covered the song and had a hit with it in 1988.
George Harrison's 1971 song "Bangla Desh" was the first major charity single. It was part of a concert held to bring relief to the people of Bangladesh, who were fighting for independence and suffering from a famine.
