If so, that's unfortunate, because having read Shout! the most interesting part of the new book to me would be the post-Beatles section.
It was a review in a newspaper, so i don't know if it is all corect what the reviewer said...
I found it again on the internet, so i will try to translate it, but i don't know if it is good English.
The negative part from the review:
It is remarkable how Norman describes the late Beatles-years. As if he knows that about the period - and after Shout also a lot of good thing - is published, and he could better not venture another exegis to Lennons texts. Because Ian MacDonald in Revolution In The Head did that already.
Norman also describes the Dakota Years detached.
Where Norman tried so hard to speak Lennons studiemates en friends from Hamburg, it seams that he lost his interest for Lennons later years.
Unfortunately, because the firtst 200 pages about Lennons youth in Liverpool are wonderful. But when the Beatlemania starts, Norman lost his acerbic.
I really don't know if i translate it correctly (mainly acerbic...), but i hope you can understand it.
