People are lining up outside the Chicago Theatre, where Charlie Sheen is expected to perform.
People outside the theater are saying they have low expectations for Sunday night's show after what they heard about Sheen's show Saturday night in Detroit.
Sheen was heckled, booed and eventually abandoned by the crowd at his inaugural stage show. Many audience members in Detroit chanted "refund" and headed for the exits even before the show abruptly ended.
Twenty-three-year-old Katie Iglehart of Chicago said she was nervous about Sunday's show. She said she figured she would see what happens, and if it's bad, she planned to leave.
