When did you first start to listen to AC/DC? What is you favorite song?
I first started when I was a little kid since my parents listened to them. My favorite song is Rock and Roll Ain't Noise Pollution.
That song is great! The lyrics go like: Hey there, all you middle men. Throw away your fancy clothes. Those are really interesting lyrics.
Yeah it's a great song, and a commentary on how the music they produce isn't low quality and doesn't just ruin the radio when it's on.
Are you interested in any other Old School Rock groups, like Led Zeppelin? 
Led Zeppelin and Lynyrd Skynyrd are both great bands as well. I like most of the more well known 80's rock bands.
How long have you been a fan of these bands? They don't seem to be as popular these days
Since I was a kid, 20 years ago. My parents favorite genre was old school rock and roll so they played all those bands. KISS, White Snake, Rush, and so on.
Oh, I haven't heard of some of those. Are they similar to ACDC?
Yes, a little less hard rock and a little more alternative maybe but they're relatively similar bands.
