Iron Maiden frontman Bruce Dickinson spoke in an interview with New Zealand TV Show “The Project” and explained how he decided to do one-man speaking show. He said:

The show I do, basically, it’s a one-man show. And it morphed out of being initially promo for the book. The publisher said, ‘We’re gonna rent a little theater and you just do some readings,’ and I thought, ‘Well, that’s kind of dull, really.’

So, years ago, when I was an undergraduate in college, my then-girlfriend persuaded me to go and see a one-man show by a guy called Quentin Crisp.

So I had to be dragged along: ‘Oh, who is this guy?’ Anyway, it was absolutely brilliant. And one of the things he did in the second half was he took cue cards from the audience who wrote questions down, and he basically came and did almost like an improv thing where he answered the questions.

So I thought that would be nice to do. So I sort of constructed this show, as it were, and just winged it. And it was so good, they asked me back to do the Edinburgh [International Book] Festival.

And then the next thing after that was I’ve ended up doing a bunch of them in Scandinavia, and I’m now doing Israel and Greece and more shows in Scandinavia and everything else. So, all of a sudden, I’ve got myself this little extra gig.”
