Angus Young

I have this theory about us. When we started writing our own songs, we were 17 years old. When you're 17, you write songs for other 17-year-olds. We stopped growing musically when we were 17. We still write songs for 17-year-olds.

I never thought we'd be put into any sort of historical thing. When we started as a band, it was a day-to-day thing. You sort of played a gig, you got your money and thought, 'OK, where's tomorrow's gig?' You never thought you'd get past a summer.

I wouldn't know any newer bands. We're past the pimple stage.

When we were younger and first starting out in Australia, we found that we sold more records by word of mouth because we were playing the bars, clubs, and small places and building a following. And as we got bigger, we still relied a lot on word of mouth.

My ambition was just to be able to play guitar.

Australia is the place I know best.

Riffs are a repeating thing. They come back to you. Some of the things on 'Back in Black' were ideas we had knocked around on tracks before that: 'That bit - maybe we should take a chunk of that and slug it in here.'

Go back to the very beginning, when we first started playing in local pubs. We used to play Chuck Berry covers. Every now and then, we'd slip in one of our own songs, and we found that we were getting away with it - nobody seemed to know these were original tracks.

When we were younger, playing a bar or a club, we did what we did to get as many people to like what we were doing. I wanted the person in the back of the room to like it as much as the ones in the front. That's how I've always looked at it.

I honestly believe that you have to be able to play the guitar hard if you want to be able to get the whole spectrum of tones out of it. Since I normally play so hard, when I start picking a bit softer my tone changes completely, and that's really useful sometimes for creating a more laid-back feel.

I never bothered with cars. I was probably one of the few kids in school who didn't run around with hot-rod magazines. As I would be at home fiddling with my guitar, they would be fiddling with a car engine.

I saw Deep Purple live once and I paid money for it and I thought, 'Geez, this is ridiculous.' You just see through all that sort of stuff. I never liked those Deep Purples or those sort of things. I always hated it. I always thought it was a poor man's Led Zeppelin.
