John Lennon and Yoke One, of course--in articles, interviews, and essays, most of which originally appeared in Rolling Stone magazine. After a hagiographic series of introductions (""I cannot think of an individual or a pair of individuals who in our time risked so much, not just once, but again and again . . .""), there are biographical sketches of John and Yoko's early lives. Then comes a breathless chronology of the John/Yoke romance, 1966-1975. Next: interviews; a clutch of pieces on the doomed Toronto Peace Festival; three reports and an interview re Lennon's immigration problems; Chet Flippo's ""The Private Years"" (1976-1980). And then: most of the contents of the special January 22, 1981 Rolling Stone memorial issue following Lennon's murder: ""Inside the Dakota,"" ""The Word Spreads,"" ""Sharing the Grief,"" ""Hearing the News""--plus tributes from Mick Jagger, Harry Nilsson, and two dozen others, Only the last section here, however, offers fresh material that might appeal to those who aren't utterly worshipful fans: in relatively, thoughtful essays, the Lennon/Yoko canon (avant-garde films as well as a great variety of Beatles and post-Beatles music) is briefly critiqued by veteran rock critics, including the reasonably level-headed John Rockwell and Robert Palmer. Chiefly a scrapbook (lavishly illustrated) for the Lennon/Rolling Stone faithful, then--with a few pages here and there of more serious rock-music-history interest.
