Martina McBride is coming to the Seneca Allegheny Casino for a show this Saturday night and I had a chance to speak to her on the show on Tuesday morning. Besides being a busy mom, Martina has a busy schedule on the road as well. She is doing a few "intimate" dates at casinos such as this weekend's show. But she will soon be a part of something much bigger.George Strait announced last week that Martina will join him on his farewell tour. What does that mean to Martina?What is her favorite George Strait song? And what can we expect from her show this weekend? I asked her that on the show....
