I can confirm that the actual Paradise Lost narrative doesn't begin until the 2:09:45 mark. I'm amazed this audiobook spends the first two hours giving biographical info, sample poems that aren't actually a part of the main narrative, etc.
Otherwise, the reader's voice is by far the most engaging, dramatic and rich among the offerings here at audible. If cost is not an issue, I'd recommend this version and skip to the time hack indicated above.
