This was a bit of real life Goodreads-style book-detective work. Not that much work really, but hey, kind of interesting to us weirdos. 
 I read this hot off the press and reviewed it saying thus : 
 Don't know if any other pop music geek already pointed this out - probably did - but it contains a major historical gaffe which amused and annoyed me - in 1962 the guy is playing his classical-music-loving fiancee Beatles and Stones records which wouldn't be released for a whole year. I bet IM is sick and tired of being told about that howler already. Serves him right! Do your homework! 
 You can see the puzzled comments of American friends below, and after some debate, it turned out that by the time the American edition was published IM had quietly fixed his mistake. Didn't know they did that!
