While not denying that retirement is something he and the other members of AC/DC contemplate, lead singer Brian Johnson tells Morning Sun Music the group intends to keep on doing what it's doing for as long as fans continue turning up in big numbers for concerts. Johnson explains, 'The thing about the boys in AC/DC, you've got to remember, is we're constantly surprised and amazed at how we keep the successs going', adding, '...we just play 100% every night and give it everything we've got', and, 'We never expect the crowds. We never take anything fro granted. How can you? Times change. You've just got to keep doing what you're doing, basically, and just hope they come back for more.' They have, as AC/DC continues to add impresssive numbers to one of Rock's biggest tours. The current run of North American dates ends with the band at Dodger Stadium on September 28.
