" As we mixed down the song “Rocket Queen,” Axl felt that the bridge needed something; some other element to elevate the drama. He suggested that Adrianna Smith, who was with us in the studio that day, fuck him in the live room so that we could record her vocals and layer them over the breakdown. We’d been drinking Jack pretty heavily all day, so it seemed like the most natural thing in the world. I was all for it; I knew too well what she was capable of vocally—she had kept me up for the past three nights. So we lit up some candles for atmosphere, then she and Axl went out into the live room, got down on the floor by the drum riser, and we recorded Smith’s performance in all of its honest moaning and groaning. Enjoy it—it’s right there in the final mix. That breakdown said it all; I couldn’t think of a better song to close the album and I couldn’t think of a more telling slice of our lives at the time to hand to our fans. "
