There is a older country song, where there is a middle aged man singing that's heavier set and wearing I believe a black cowboy hat.
The woman walks into a nicer restaurant and sits down at the bar, she kept turning back to look at her ex and his new woman. Her ex and his woman get up and walk out and she sits there and talks to the bartender and he has a thing for her.
That's all I remember. I've been searching for the song for two hours and can't find anything. :(
