It's about time: Yoko Ono will pen memoirs detailing her relationship with John Lennon, The Guardian reports. Though she's always been tight-lipped about the Beatles' final days, Ono revealed this week that she'll write a set of books on the Fab Four. They will include details on Lennon's "quirks," such as his habit of being "very particular about how to make English Breakfast tea." But there's a lot she likely won't reveal: "There are things that I can't write because it may hurt someone," Ono said in 2007. " I think about how it might hurt [their] children, and I don't want to do that." Don't hold your breath, though: Ono told fans that she would need "five years or so" to complete the first book.
