Who knew that Brian Johnson, AC/DC's front man, was writing a book? His "Rockers And Rollers: A Full Throttle Memoir" will be out on May 24th, and he's lined up a few book signings — solely back East so far, but out here soon enough. The memoir is told through Brian's lifelong love affair with cars, from teenage memories in the back of beat-up coupes to a side career as a racecar driver.
