Think what you will of Morgan Wallen, but you can't say the man doesn't have a heart for his own son. While in the UK this week, he explained to the crowd his initial reaction to the demo of his song "Superman," a song he wrote for his boy Indigo. He told the audience he had a 25 -minute drive in which he could listen to the song they just cut several times. "The very first time I heard it back after we got through writing it, I just, I just broke down, and I was crying. And that’s the first time I had done that writing a song for my little boy. So I figured if it touched me that way, then hopefully it would touch a lot of you guys the same way." "Superman" is one of the 37 cuts on his latest album, "I'm The Problem."
