In a new interview with Fortune for his autobiography, What Does This Button Do?, Iron Maiden frontman Bruce Dickinson discussed the longevity of the band as well as his career as a singer and a successful businessman. An excerpt is available below.

Fortune: Many of your 80s rock peers are touring, playing a largely greatest hits set, while a third of Iron Maiden’s set on the recently ended “Book of Souls” tour came from that album. Why?

Dickinson: "If you take advantage of them (fans) as in you serve up the same old thing every single tour, you can expect some of them to walk away. That is just a band becoming a karaoke band. If you’re not doing new music why bother? We don’t share the idea that going and doing stadiums, playing 30-year-old songs, is a success. It’s just making money."

Fortune: What about fans who don’t want you to play anything but the 1980s classics?

Dickinson: "That’s tough. In that case, don’t come."

Fortune: You’ve now been back in Iron Maiden for 18 years, far longer than the first time around. Why has it held this time?

Dickinson: "Everybody realized that the most important thing about being in Iron Maiden was that Iron Maiden was the most important thing. There are no more power struggles now."

Heavy metal pioneers since their formation in 1975, Iron Maiden have sold over 90 million albums and played over 2000 shows in 63 countries, making them one of the most successful and globally influential bands of all time. One of the world’s most storied musicians, Bruce Dickinson has been the band’s internationally-acclaimed lead singer for more than 30 years, and quite aside from the decades spent delivering high-octane performances with his larger-than-life persona, Bruce has lived an extraordinary off-stage existence too. A true polymath, Bruce is, or has been, an airline pilot and captain, an aviation entrepreneur, a beer brewer, motivational speaker, film scriptwriter, twice-published novelist, radio presenter, TV actor and a world-class fencer.

Over the last couple of years, and throughout Iron Maiden’s The Book Of Souls World Tour, which has covered 39 countries and 117 shows since February 2016, Bruce has turned his unbridled creativity to writing his memoirs, longhand (in seven A4 notebooks no less).

In What Does This Button Do?, Bruce (a man who famously never gives interviews about his personal life) shares, for the first time, the most fascinating recollections, including his thirty years with Maiden, the early days, his childhood within the eccentric British school system, going solo, realising his dream of flying jumbo jets and his recent battle with tongue cancer. Bruce Dickinson is so much more than the frontman of one of the biggest bands on the planet. A rock icon, a true renaissance man, Bruce has been, and remains, a man of legend.

Bold, honest, intelligent and very entertaining, What Does This Button Do? is the long-awaited window into the life, heart and mind of one of our most adventurous and multifaceted sons.
