Firstly, Amazon's listing is misleading. This is NOT an audiobook. It is just a book. A great book for sure, but there is no CD or DVD, and never was. Ian Gillan's PA told me (via email), "No there wasn't ever a CD with 'Smoke This'." Ian himself writes in the Foreward, "I have no idea what this book is for - oh yes! I remember now. It's supposed to contain a CD called Gillan's Inn. But that particular item got tarted up and coupled itself with a DVD [it became a dual disc] containing tons of intimate material delivered electronically, so rendering the book lonely and isolated."
So now you know! Anyway, buy the book because it's simply great. Mr. Gillan has a sparkling sense of humour and it contains many fun and fascinating writings, lyrics, musings, and an array of great photos (many in colour), taken from throughout his career and all printed on large format, glossy paper. It is by no means a biography, and was never intended to be, but it is no less interesting and relevant.
Also if you're wondering about the Gillan's Inn dual disc, personally I'd recommend it. It has an array of guest musicians including some Deep Purple members and is packed full of expertly written and played music, plus loads of other extras. It does make a nice companion to this book too.
