Sir Paul McCartney is jetting from New York City to Las Vegas, Nevada, today (15JUN06) for a preview of the forthcoming Cirque du Soleil production inspired by THE Beatles' music. The veteran singer, who turns 64 on Sunday (18JUN06), is currently on a brief business trip to the United States, but hopes to return to England this week to celebrate his birthday with his four children. MCCartney will be enjoying an exclusive sneak peak of the show, which is set to premiere at The Mirage hotel and resort on 30 June (06). The LET IT BE hitmaker will join former Beatles bandmate Ringo Starr at the opening night, as well as the widows of late bandmates George Harrison and JOHN LENNON - OLIVIA and Yoko Ono respectively.
