I just happened to stumble upon while browsing the Bucket List Listens page. It doesn't show up in a search of Richard's name on audible. Nor does it show up under a search of the author's name.
It may be the Audible Christmas gift to US members as the same book narrated by Jennifer Saunders is the gift to UK members.
I'm not sure, though. I'm just glad I found it when I did.
