He'll be playing Phoenix on March 28th and then the Hollywood Bowl on March 30.  Tickets go on sale this weekend at Ticketmaster (and at Live Nation but it just redirects to you Ticketmaster so there's no point.  Isn't the Free Market GREAT!).

He will most likely play a combination of tracks from his solo work, Wings, and of course several songs from the Beatles catalog.  If it's anything like his performance at last year's Coachella then it should be an amazing show.  That performance was one of the best shows I've ever seen and I've been to a bunch of shows.
