Halford tells OC Weekly: "I always listen to Ronnie before I go on stage with Priest because I find his voice invigorating. It gets my blood pumping and gets me in the zone before I go out and do my thing with Priest. I pretty much listen to him almost every time.

"I listen to Ronnie for so many weeks at a time. I find his voice so inspiring and so powerful for me as a singer. He was a very influential singer. If you listen to him now, you can almost imagine what he was like behind the mic in the studio because he's so committed.
