The Triplets Get Their Break
Barry Manilow is joining the likes of Elton John and Celine Dion, preparing for his huge opening night at the Las Vegas Hilton, and he gave "Extra's" Terri Seymour a backstage tour.

"I really didn't know it was going to be one of the most anticipated shows in Vegas," the modest Manilow admitted. "It's an honor to be on the same street as Elton and Celine and have my own room at the Hilton."

Barry's final dress rehearsal was in front of a packed house that included none other than Diane Sawyer, who actually joined Barry on stage for a surprise duet.
