Vince Gill performed his second concert as the Country Music Hall of Fame and Museum's artist-in-residence on Tuesday night (Feb. 17) at the museum's Ford Theater. Along with numerous selections from his catalog, Gill offered a few new songs and also invited his longtime friend, singer-songwriter Guy Clark, on stage to perform. Explaining the stories behind several of his newer songs, Gill told the audience that "The Lucky Diamond Motel" was inspired by growing up about a mile from Route 66 in Oklahoma. In addition, Gill credited his wife Amy Grant as a co-writer of "Heaven" and said he wrote "Forever Changed" about his anger at adults who hurt innocent children. After Gill invited him to the stage, Clark announced that he has completed a new album and previewed it with two new songs, "Some Days the Song Writes You" and "Hemingway's Whiskey."
