He is now a New York Times Best Selling Author, having published a children's book.
This is a two-page article on Wired, I'm linking directly to page 2, which is the interview. Page 1 is intro and a review of an interactive iPad game version of his book.
http://www.wired.com/geekdad/2011/07/weird-al-interview/2/I think I must be getting old. I picked up his two most recent CDs last week and listened to his previous album, Straight Outta Lynwood, and I didn't recognize a single song from his polka medley. And I only recognized his Trapped in the Drive Thru because of the Southpark Scientology episode.
I expect similar results when I listen to Alapalooza.
