For the fifth time in their careers, Chicago and the Doobie Brothers will tour together. The two classic rock bands will be on the road playing mostly sheds and amphitheaters for 25 dates across the country between July 11 and August 26. Chicago are the headliners, but the show promises to have both bands on stage for the finale playing some of their biggest hits.

Chicago is working with the American Cancer Society to raise funds through their "Sing with Chicago" program. Fans can bid to win a VIP package that includes two premium tickets, a meet-and-greet with Chicago and the opportunity to sing 'If You Leave Me Now' on stage. This is the third time Chicago has partnered with the ACS.

In addition, a portion of every ticket sold will go to two charities: the Ara Parseghian Medical Research Foundation, which raises funds to find a treatment for Niemann-Pick Type C and other neurodegenerative diseases, and Hannah & Friends, which helps adults and children with special needs.

Following the tour with the Doobie Brothers, Chicago will continue their American tour. They plan to tour Asia in the fall, with other dates around the world to follow in the near future.
