Music can always be a life-changing experience, for musicians and fans, or at least life-affecting, but it depends on to what degree.

No. I usually rest in my satin-lined coffin, actually. I'm not allowed out in daylight hours.

Every musician wants to do something which will hold up for a long time, and I guess we did it with 'Stairway to Heaven.'

I really wasn't needed... Just straightening up riffs, that's all. Just two guitarists doing it instead of one.

I suggested back in 1980 to do a chronological live album, but there wasn't that much enthusiasm for it.

There was no working title for the album. The record-jacket designer said `When I think of the group, I always think of power and force. There's a definite presence there.' That was it. He wanted to call it `Obelisk'. To me, it was more important what was behind the obelisk. The cover is very tongue-in-cheek, to be quite honest. Sort of a joke on 2001. I think it's quite amusing.

Every record is a portrait of the band at that time.
