But you know what else was totally wild? The classic rock era and its rock stars. So I thought I’d ask the BuzzFeed readers: What's the coolest, wildest, or even the most bizarre fact you know about the classic rock era (which, for the sake of this post, let’s call 1955–1989)?
Maybe your crazy fact is that Jerry Lee Lewis (the high-energy pianist/singer behind "Great Balls of Fire") had his career derailed when it was discovered that he was married to his 13-year-old third cousin.
Or maybe you were shocked to learn that Canadian folk/rock legend Neil Young and American funk superstar Rick James were in a band together before they became famous for very different styles of music.
Perhaps you can't get over how Jefferson Airplane's lead singer Grace Slick — after being invited to the White House — went with some acid and a plan to dose President Nixon.
