1. Yes, a fully annotated collection of all his lyrics (with variations) would be lovely; however, between the temporarily-defunct PassionsJustLikeMine and a copy of Mozipedia, you can have the same effect.
2. No autobiography this fall. A deal would have been announced loudly, and I have heard nothing on the publishing grapevine, either. The book would probably be due from the author very early in a year (February or March) for release that fall unless it's being rushed to print as a celebrity tell-all. I can't fathom that; it will be well-edited and treated with dignity. So maybe next year? I've no idea how they prefer to time things like this--maybe key it to an anniversary or a birthday? Perhaps late summer, the 26th anniversary of the Smiths' breakup?
