Here is more or less how it went.
1) Simon Pegg wrote an autobiography? Bring the humor!
2) I can also check out the audiobook, voiced by Pegg himself? Most excellent!
I then listened to the first third of the book on a long drive. Arriving at home, I cracked open the book to read footnotes and glance at photos, and quite soon found parts I hadn't heard.

That's right, the Simon Pegg audiobook is abridged.

Five stars for content, minus a half because the first part jumps around chronologically, minus a full star for the abridgement (Why, Simon, Why?!?), and finally plus a half star for being, well, Simon Pegg.

The full book is recommended if you can imagine Simon's voice reading it (I know I can) with Nick Frost occasionally muttering profanity.
