This is must-see YouTube! Behind the scenes with AC/DC and the story of "Back In Black". So cool to hear the stories behind these monster songs from this MONSTER album! The creative process is fascinating. How different "You Shook Me All Night Long" would have sounded if Brian Johnson has listened to the first critique. Really cool stuff. Can't wait to see all of the episodes in this series. Can't believe it's already been 40 years! Click HERE to see the video. (WARNING: PROFANITY. NSFW) (Photo by Kevin Mazur/Getty Images)
