Charlie Sheen -- The Show Will Go On!

[Walter Cronkite]

Despite the disaster in Detroit last night, Charlie Sheen is moving on to Chicago for tonight's performance ... sources connected with the show tell TMZ.

The way Charlie's people see it ... it was just "one group of unruly people who started booing, and it became a mob-mentality situation."

One source groused, "They wouldn't even let him finish a story," adding, "It wasn't all bad and we're looking forward to Chicago."
