John Lennon's ex-girlfriend MAY PANG is set to release a book of previously unseen photos taken of the late beatle during their 18-month romance. The book, titled Instamatic Karma in reference to Lennon's song Instant Karma!, features 150 photographs of the Imagine singer, including shots of him in the studio recording his album Walls And Bridges, and images with his Fab Four bandmates Sir Paul MCCartney and Ringo Starr. Lennon dated his assistant Pang in 1973, when the star had temporarily separated from his wife Yoko Ono. Instamatic Karma will be released early next year (08).
