The song (listen above) is seven minutes of pure bliss. Mick Jagger opens with powerful vocals that are set to a soothing arrangement by Wonder. “I hear the sweet, sweet sounds of Heaven, fallin' down, fallin' down to this earth,” he sings.
Gaga makes her debut at the 1:50 mark, but if you aren’t expecting it, you may mistake her for someone else. Her voice is nearly recognizable as she echoes Jagger’s lyrics in a soft, high-pitched tone.
In an interview with Sky News, Stones member Ronnie Wood explained how the collaboration came to be. The band was working on a different project when they crossed paths with Gaga, who was also in the area for work. “She was sitting on the floor in the studio, and Mick said, ‘Don’t just sit there and hum. Get up. Let’s record this,’” Wood recalled. “She’s lovely. She’s very talented.”
