I love this book, his writings about him and Yoko, the Beatles breakup, Peace, his battle with the US government are very revealing.
But the book is a treasure because of the many "Lennonisms", such as:
"why did the chicken cross himself"
"always a bridesmaid, never a couplet"
"if you can manicure a cat, can you caticure a man?"
"Maurice finished his donut, tipped over the waitress and headed for the door."
"this is my story both humble and true
take is to pieces and mend it with glue"
There's so much more, if you love Lennon, you'll love this book.
