LAS VEGAS » Celine Dion has returned to the Las Vegas stage in a parade of sparkly dresses with thigh-hit slits, a stage full of trumpeters, violinists and drummers, and a special appearance by Stevie Wonder.

The French-Canadian crooner sang the romantic opuses that made her an international star, including "My Heart Will Go On" and "It’s All Coming Back to Me Now," in her encore performance Tuesday night at the Colosseum at Caesars Palace. She also shared a pre-recorded duet with Wonder to his "Overjoyed."

"Was that neat or what?" Dion told the concert hall of more than 4,000 people as a hologram of Wonder faded from the stage.

A lot is riding on this sequel performance. Dion, who gave birth to twin boys nearly five months ago, is tending to an expanded family while trying to mirror or surpass her previous success in a city that has yet to pry itself free from the embrace of a brutal recession.

The new three-year production pays tribute to Old Hollywood, with a 31-person orchestra dressing the stage, including an entourage of guitarists, back-up singers, drummers and a pianist, all clad in black tuxedos and gowns.
