Carter has been performing her own shows as well, but being part of the "Plain Spoken" tour has enabled more audiences to see her, including some who may be getting a new exposure to country music. "It's hard out there on the road. There's such a saturation," Carter said. With another musical legend like Mellencamp, who will be 65 on Oct. 7, "I get to get back in front of a lot of people." The "Plain Spoken" tour has been such a success that it is coming up to 120 shows, Carter said. Expect more Carter and Mellencamp in 2017. "We'll be on road next year, spring/early summer. The show will be different at that point," Carter said.
