The troubled star was clearly stunned when the opening night of his My Violent Torpedo of Truth/Defeat Is Not an Option tour saw him being heckled in Detroit.
So by the second night he had completely scrapped the format and got in help to produce a totally different show.
Sheen cut rambling rants about warlocks, bizarre video clips and musical acts and even a movie viewing. In their place came a very simple, stripped down Q&A format - with a professional radio DJ running the show and working hard to keep him on target.
Interviewer Joey Scoleri made sure Sheen kept talking about the things fans would most like - tales of sex, drugs, Hollywood anecdotes about friends like George Clooney, and him admitting he would happily go back to work at hit show Two and A Half Men.
And while it was a long way from Sheen's claims of it being 'the most epic night in Chicago f***ing history', it ended with many fans giving a standing ovation.
