Fans who love Chicago's single "If You Leave Me Now" will have a shot to perform that 1976 hit live on stage with the band. The group has partnered with the American Cancer Society for the promotion, "Sing With Chicago." The fundraising idea allows fans to bid via eBay for the chance to sing "Leave Me Now" live on stage with Chicago on a date during the group's U.S. tour. The winning bid will be donated to ACS.
