LAS VEGAS » Celine Dion’s husband protected her from the gritty business details of her career as he struck the deals that defined her superstar status, including saying yes to her mega hit from “Titanic” when she wanted to say no.

The singer spoke publicly Wednesday night for the first time since Rene Angelil died, paying tribute at a memorial at The Colosseum at Caesars Palace in Las Vegas. She said her late husband and manager kept her grounded and always looked out for her.

“I was never part of any of the meetings that he had where he had to say yes or no. He protected me from Day 1,” Dion said in a nearly 20-minute speech.

Angelil was credited with the business decisions that made Dion one of the world’s most popular voices, from agreeing to do the “Titanic” song “My Heart Will Go On” when critics doubted the movie, to the singer’s glitzy Las Vegas Strip residency.

He died Jan. 14 after a long battle with throat cancer in the suburban Las Vegas home he shared with Dion and their three children. He was 73.

At his Jan. 22 funeral at the Notre-Dame Basilica in Montreal, their son, René-Charles, gave the eulogy to a crowd of nearly 700 people before Angelil was buried at the Notre-Dame-des-Neiges cemetery in a private graveside ceremony. The family on the previous day spent nearly seven hours greeting fans and mourners at a public visitation at the same Canadian church.

Dion, wearing a shoulder-baring black dress and her hair in a soft bun, didn’t sing during the Las Vegas memorial, but her famous discography was on display throughout the night. An instrumental version of her 1990s hit “Because You Loved Me” played as one of the interludes between speeches at the event that ran for more than two hours. Longtime friend and collaborator David Foster sang “The Color of My Love,” a nod to the couple’s song at their wedding 21 years ago, which left Dion in tears.

Mother and son sat on stage along with Angelil’s other children from previous marriages and his brother, as memories were shared from guests ranging from Dion’s longtime agent and friends in the music business to Caesars executives and a Las Vegas charity for people with disabilities.

They all described a man who was kind, generous and completely devoted to his wife and her talent. Angelil loved his family, gambling and dining and entertaining.

Born in Montreal to a Canadian mother and Syrian father, Angelil was a former-singer-turned-manager who discovered a 12-year-old Dion and mortgaged his house to finance her first album.

He guided her career most of her life, most critically as she learned a new language to sing in English to become a widespread international success. By the late 1990s and 2000s, her soaring voice had become dominant on the radio.

And to underscore his influence, longtime associate and friend Paul Farberman said at the memorial that the “Titanic” deal was far from certain when Dion was first approached to sing the theme song. She rolled her eyes when she first heard it played on the piano, and there were questions about the negative press the movie had gotten on reports that it was over-budget and had on-set fighting.

“It didn’t look like this was going to be a big success story,” Farberman said of the movie. “And I’ll never forget how Rene literally stood up from the table and he said, ‘I’m a gambler, and I’m going to bet on this one.’ And of course, the rest is history.”
