Calendar* Correction: John Lennon and Yoko Ono Press Conference

You will see several websites saying that John Lennon and Yoko Ono held a press conference to discuss their side of the story in the United States Immigration Department's attempt to deport John on April 2, 1972.  Lennon was not ordered to leave the U.S. until March 23, 1973, so that alone would make the 1972 claim nonsensical.   According to the book The John Lennon Handbook:  Everything you need to know about John Lennon by Emily Smith, the correct date is April 1, 1973.
