Billy Dee Williams lived an interesting life and if you're a fan, I'd say that makes it worth checking out. He's had a fairly accomplished career in acting when there weren't that many other men of color in Hollywood.
As far as an audiobook goes, there's a lot of name dropping and sometimes it sounds more like a resume than a memoir.
There are other times when he's so clearly moved by the subject, it's really nice to have the voice along with the words.
