I don't like that..And then as soon as we uh hit a couple chords that she liked, we started rolling, and that's where we got that song from.""There was a moment when she was singing in the booth and I'm not exaggerating at all and the water was vibrating... like you know that scene in Jurassic Park... She's got some pipes on her, and she's just a superstar."
