Underwood plays on this fall

Billy Currington and Sons of Sylvia to appear as special guest opening acts for the tour, which starts in late September. The last date is Dec. 19. Underwood launched the tour March 11, ending it in late June with a few summer dates.

Tickets for the newly announced fall dates will go on sale beginning Saturday, April 24 at 10 a.m. Underwood will donate 36 cents of every ticket sold for the fall tour dates to Save the Children's United States Programs. This initiative was inspired by the "36 cents" written in the lyrics of her album track "Change," which addresses how even the smallest bit of spare change that one might have can add up to make a difference and help "change" the world. Fans can see Underwood perform this song, "Change," on Idol Gives Back this Wednesday, April 21. Save the Children is also a beneficiary of Idol Gives Back.
