NASHVILLE, Tenn. – Before there was Shania Twain, Celine Dion or Avril Lavigne, there was Anne Murray – a pop-country crossover star who paved the way for female singers to emerge out of Canada.

“The odds were against me, coming from Nova Scotia,” said Murray, 64. “When I was a kid, it was just a wild dream to think that I would’ve had a career like this, and I really didn’t think that was possible. But things just kind of started to roll ... and I went with it.”

In her autobiography, “All of Me,” released last year, Murray reflects on her 41-year career in music. She was the first Canadian female singer to reach No. 1 on the U.S. charts and also the first to earn a gold record, for “Snowbird” in 1970. Murray was also the first woman and first Canadian to win “Album of the Year” at the Country Music Association Awards, for her 1984 CD “A Little Good News.” Her albums have sold more than 54 million copies. She might be best known for her ballad “You Needed Me.”

“The year that I won the Grammy for best pop vocalist (in 1978) was probably a highlight in my career because it really said something for me that I was crossing over all of those lines and that people saw that,” she said.

“A lot of people want to put you in a slot. They want to categorize you,” she added. “So I fought that, because I liked all different kinds of music. If I heard a good country song, like ‘Could I Have This Dance,’ or ‘Somebody’s Always Saying Goodbye,’ I wanted to sing it, a great song like that.”

But success didn’t come without sacrifice. Touring in the United States forced her to be away from her kids, Dawn and William Langstroth, for long periods.

“I started to take them on the road with me, but both of my children developed ear problems. I couldn’t take them. They had to have tubes in their ears. They couldn’t fly,” she said. “So it was hard for me to leave them behind, and I did. And both of them felt it.”

The demands of her career also put strain on her marriage to Bill Langstroth.

“When I was going through all the divorce things, that was really hard to discuss, because nobody wants to talk about their failures,” she said. “Nobody wants to talk about how painful those things are.”

Ultimately, Murray is thankful for what she calls “a wonderful career.” Her most recent CD, “Anne Murray’s Christmas Album,” released in 2008, featured a duet with Michael Bublé.

She suggested that the album might be her last.

“I’ve been doing it for 41 years,” she said. “I’m grateful that I feel comfortable in the fact that I’m not going to be doing it anymore, and I didn’t know that I could come to this, but I can still sing, and what better time to pack it in than that?”
