I heard him in an interview talk about the earpieces really helping and getting sober. He said before the earpieces he used to shred his voice every night because he had to scream to hear himself. Now he can have a great mix of the band in his ear and being able to hear himself really saves his voice. He also said instead of a line of coke between songs its tea with honey or something.
Woah, love that Andy Sneap was given the lead on this one! Priest are a twin lead band, and I've long felt that Andy should be given more of the lead work to be a true tag team with Richie. They really dropped the ball though, not having Andy taking some of the lead duties on the latest Priest record.
