The older sister of George Harrison is writing a tell-all memoir about her famous brother and his band because “so much garbage has been written about George and the Beatles,” 80 year old Louise told the Sarasota Herald-Tribune. Louise has finished most of the text for the book, which should be released next year or 2013. Now she’s scanning never-before-published photos, letters and documents that will fill the rest of the pages.

“Half of the stuff [out there] has been written by people who spent maybe an hour on a plane with the Beatles. Now I think it’s my duty to get the truth out. There’s been all kinds of myths and fantasies written about them. I have some facts to go on, because I was there, from even before they were the Beatles.”

Not only was Louise there before they were the Beatles, she even played a small part in breaking the band in America, where she was living in the early-’60s. “I would relay information over to (Beatles manager) Brian Epstein,” she says. “I told him that the Beatles weren’t getting any airplay over here, that they really needed to play on ‘The Ed Sullivan Show,’ which they had never heard of.”

Louise has numerous stories to share about George, including claims that his “Quiet Beatle” nickname came about simply because he was so sick when the band first came to America that he “was told to use his voice as little as possible.” Louise doesn’t want to reveal too much just yet, however. “You’ll have to read the book,” she says.
