It's funny to see the drastic different opinions the band members have sometimes. While Nicko wants orchestral versions of some Maiden songs, Bruce said:
"If we did “Empire” like that with an orchestra, I would not call it Iron Maiden. I don’t know whether the guys would be interested; one or two of them might be. But I wouldn’t call it Iron Maiden because it wouldn’t be us. I think a lot of these things with orchestras, I think people have a sense that they want to be sort of like “real musicians,” and somehow being there playing with an orchestra somehow validates them more than it being metal musicians; that’s absolute nonsense.
But there are times when an orchestra is just so powerful. But what it does do, is it obliterates the band. I’ve never heard an orchestra that hasn’t completely overwhelmed the band it was playing with.
And also, just doing orchestral backing music to a rock track is utterly pointless. It’s just kind of musical narcissism. An orchestral version of Nirvana? Oh, get out of here! Why? So if you wanna write something that uses an orchestra and requires an orchestra, different story. Different story. No, doing orchestral versions, “50 Iron Maiden Greatest Hits Played by the Bulgarian Symphony Orchestra” No! No, never!"
