For both artists, it was an experience to remember.
Cole, McCullough, choir director Mack Wilberg and choir president Mac Christensen spoke at a press gathering at the Conference Center Friday morning.
"They are great," the Grammy Award-winning Cole said of the choir and orchestra. "One of the things that I was really impressed to discover was that these are all volunteers. I've worked with a lot of people through the years, a lot of choirs and churches, as well. I tell you this is as professional as it can be. Their willingness to do well ran throughout the performance."
"I think Natalie said it perfectly," McCullough said. "(It) is so gratifying to be your guest. I am not accustomed to being in front of 21,000 people. And I'm not accustomed to a big orchestra and chorus behind me. When I stood out here last night on the edge of the stage, all of a sudden this sound started behind me and I almost fell off the stage.
"I thought that would be a perfect entrance to my experience here."
