She talked about what makes the marketing arrangement work ("They're the old country store. I'm the old country girl"), working with Queen Latifah in "A Joyful Noise" ("We like each other. Complete opposites, but we found we were very compatible. I always loved watching her"), and some of the desperately sad songs she penned early in her career ("It was in my Smoky Mountain DNA to sing and write those God-awful pitiful songs!).

The country icon also said she is honored that one of her songs, "I Will Always Love You," has become a memorial to the late Whitney Houston.
"I think it's wonderful," she said. "I thank God, first of all, for that song. I thank Porter Wagoner second. But I thank Whitney Houston for doing such a performance on that song. I have never heard a better performance than that on anybody's song by any artist. That song is the link that put us together and I think it's wonderful."
The concert album, recorded in London, is on sale now at Cracker Barrel. "A Joyful Noise" has earned nearly $31 million since its mid-January release, according to Box Office Mojo.
