was dedicated to Lennon's mother, Julia, who had died when he was a teenager. According to Ono, the work was meant to be innocent, not shocking; she was attempting to replicate the experience of a baby looking up at its mother's body, those parts of the mother's body being a child's introduction to humanity. Ono performed at the opening ceremony for the 2006 Winter Olympic Games in Turin, Italy, Like many of the other performers during the ceremony, she wore white to symbolize the snow of winter. She read a free verse poem calling for world peace as an introduction to Peter Gabriel's performance of "Imagine". On December 13, 2006, one of Ono's bodyguards was arrested after he was allegedly taped trying to extort $2 million from her. The tapes revealed that he threatened to release private conversations and photographs. His bail was revoked, and he pleaded not guilty to two counts of attempted grand larceny. On February 16, 2007, a deal was reached where extortion charges were dropped, and he pleaded guilty to attempted grand larceny in the third degree, a felony, and was sentenced to the 60 days that he had already spent in jail. After reading an unapologetic statement, he was released to immigration officials because he had also been found guilty of overstaying his business visa. Ono released the album Yes, I'm a Witch in February 2007, a collection of remixes and covers from her back catalog by various artists including The Flaming Lips, Cat Power, Anohni, DJ Spooky, Porcupine Tree, and Peaches, along with a special edition of Yoko Ono/Plastic Ono Band. Yes I'm a Witch was critically well received. A similar compilation of Ono dance remixes entitled Open Your Box was also released in April.
