Alan Jackson has his own version of the 1 percent vs. 99 percent problem, and he has to contend with it every night he’s on tour. “The problem with me is I’ve had 60-something singles,” said the lanky country singer and songwriter last week from his home outside Nashville. Jackson, 53, was gearing up for a West Coast swing. “It’s gotten to be that there are so many songs. … It always ends up I leave something out that somebody wanted to hear, and I feel bad.” It’s a problem that maybe 1 percent of working musicians face and a problem most would give their eye teeth to have. In fact, Jackson has charted closer to 70 singles over more than two decades, about 50 of those reaching the Top 10, which include No. 1 hits such as “I’d Love You All Over Again” in 1991, and his latest, “As She’s Walking Away” on which he duetted with the Zac Brown Band. His latest album, “Thirty Miles West” takes its title from the distance between his hometown of Newnan, Ga., and the fabled Dixie Highway that runs through the South. He also says he’s still hankering to record a straight bluegrass album — a project he started about six years ago with bluegrass queen Alison Krauss producing, but which morphed into a critically acclaimed atmospheric adult country album, “Like Red on a Rose.” … Rascal Flatts bassist Jay DeMarcus and his wife Allison have a new addition to the family. The couple’s second child and first son, Dylan Jay DeMarcus, was born Friday afternoon in Nashville, Tenn. Dylan weighed 7 pounds, 11 ounces and was 20½ inches long when born. A news release says mother and child are doing fine. He joins 1-year-old sister Madeline Leigh. DeMarcus has a little time at home with his family before hitting the road again Friday in St. Louis for the trio’s “Changed” tour.
