I got my copy last week, and have been listening to it over the week-end. I think this will be his swan song. It sounds like he really put his heart into it, unlike something like Shadows in the Air, which seems to lack any enthusiasm.
This is an album of songs, and focuses more on vocals and keys more than his bass. The bass is there, though. Big and fat, not like the farts of history. It's a really good album, with its highs and lows. You can tell when Jack was feeling good and not by the vocals. There are a couple where he sounds pretty weak. My favorites, so far, are probably "Fields of Forever" and "Rusty Lady".
Another strong one is a remake of "Keep It Down" from Out of the Storm.
