More than 20 years after a plane crash killed seven members of her band and her tour manager, Reba McEntire can still clearly see the hotel room she was in when she got the news. The emotion comes flooding back when she revisits that tragic day in 1991 on “Oprah’s Master Class” on the OWN network Sunday night. It’s a rare break in composure from the queen of country music. “I don’t guess it ever quits hurting,” she says on the show, recalling how she tearfully followed husband-manager Narvel Blackstock room to room as he called people to let them know. “It’s the worst thing that’s ever happened in my life.” From that tragedy, she learned to make each day count and not to put anything off until tomorrow. However, McEntire said after the crash, she built up a wall so she would not get close to anybody, and it took time for her to open up to members of her touring family again. She accepted support from industry friends like Dolly Parton, who helped her put a new band together, and she took solace in her strong work ethic. Hard work has served McIntire “tremendously” throughout her career. McEntire is now a member of the Country Music Hall of Fame and has sold more than 55 million albums worldwide. She also runs a successful fashion and merchandise line. In 2001, she performed in the Broadway revival of “Annie Get Your Gun” and she starred in the hit TV show “Reba” for six seasons before it was taken off the air. This year, McEntire is going back to television. ABC has picked up a pilot for the show “Malibu Country.”
