''It started off from a little trick I had on guitar. I played it to Mal and he said 'Oh, I've got a good rhythm idea that will sit well in the back.' We built the song up from that. We fiddled about with it for a few months before everything fell into place. Lyrically, it was really just a case of finding a good title ... We came up with this thunder thing, based on our favourite childhood toy ThunderStreak, and it seemed to have a good ring to it. AC/DC = Power. That's the basic idea.'' - Angus Young
''Before the band performs it live, I have to sit down for an hour and make sure I've got my fingers warmed up to take on that track. It's got an unrelenting intricacy. I have to be confident whenever I play it." - Angus Young
