Conversations With Tom Petty has landed in bookstores today. There are a few Jeff-related surprises in the book, but at the risk of spoiling them, I'll tell you it's probably better for you to just pick up a copy and thumb through. There's actually a great deal of Jeff Lynne related material in the book.
What's more interesting is that the book's epilogue has (from what I can tell) a track by track discussion of his new Highway Companion album. The track list is practically laid out. So, the album must not be too far behind.
