This book is divided into two major sections. The duties section occupies the first 61 pages, and is a précis of everything leading up to the speech, and also a few notes on the honeymoon. It doesn't go into any detail at all about anything really.
For example, choosing the ring, a very important part of the buildup, has only two pages devoted to it, and it says precisely nothing. However, this book does go into some detail about your choices for the ceremony (and presents it from a British, not American, perspective), and how to tie your bowtie (seriously!). For better coverage of everything except the speech, even though I disagree violently with some of it, I much prefer "The Clueless Groom's Guide: More Than Any Man Should Ever Know About Getting Married" for its better and more detailed coverage.
The second part of the book gives great detail about your speech, including 15 sample speeches and a lot of jokes. If you need a lot of guidance -and I do mean a lot of guidance - in writing your speech, then here you have nearly 100 pages of examples. However, I do find this a bit OTT
Personally, I think the central section between pages 64 and 83 are what most people need, and I find it better presented in Confetti's own book "How to Write a Wedding Speech". The advantage of that book is that you can also see what other people in your party are likely to say and when they are likely to say it, and so you can avoid covering their material in your speech. This has the effect of making your speech more punchy and, to the relief of everybody in the audience, shorter.
In conclusion, only buy this book if you think you need a huge amount of help in your speech. Otherwise, I recommend buying the two other books mentioned in this review.
