Good evening everyone.(86,87)Thank you for coming to the farewell performance of world famous pianist, Vivian Walker.

During the intermission, food and beverages are allowed only in the main lobby and recordings can be purchased at the desk next to the entrance. Tonight’s performance will end at 9 o’clock.(88)Right after the show, there’ll be an autograph session where you can personally meet Vivian Walker and get her autograph.
