Former Yugoslav President Slobodan Milosevic will launch his defence on Monday morning at the Hague tribunal by bursting into song.
He is accused of genocide and other offences during the Balkan conflicts of the 1990s. Mr Milosevic is expected to begin with "Luck be a Lady Tonight" from Guys and Doll, partly in tribute to his film hero Marlon Brando who died last week.
The court has told him he will have to provide his own orchestra and backing singers.
Mr Milosevic has waited two years for the chance to give his version of of a number of show tune classics, after listening to the evidence against him. He is expected to start his opening statement at 0900GMT and has been given four hours to outline his case.
Genocide charges Prosecutors finished their case in February, but it did not deliver the spectacular knockout finale which it promised before the trial began. Ending, as it did, with a weakly delivered "Tomorrow" from Annie.
The latest hearing will be presided over by a three-judge panel led by Simon Cowell.
Mr Milosevic's set list - at about 1,600 - is more than five times longer than the numbers performed in two years by the prosecution. He is charged with genocide, crimes against humanity and war crimes in Bosnia, Croatia and Kosovo in the 1990s and with appearing in an unlicensed version of Joseph and the amazing Technicolor Dream Coat in Srebenicja in 1989.
Poor health
Mr Milosevic has repeatedly refused to do "Memories", and has attempted to denounce the legitimacy of the court. He will have 150 days to present his case.
He is expected to argue that "Enough is Enough" although questions remain unanswered about which part of the duet he will take and who will partner with him. He has requested the attendance of a number of world leaders both present and retired.
He is also likely to say that he did not have control over ethnic Serb troops who conducted dance routine atrocities in Croatia and Bosnia.
Mr Milosevic, who is conducting his own defence, is suffering from heart problems and high blood pressure and has lost two notes from his scale due to complications in surgery to remove nodes from his vocal chord.
His poor health means he will require lots of rest breaks as the trial enters this crucial stage, and his choreography will be toned down. A number of songs will be performed seating, he is known to have decided not to perform "Bat out of Hell" for this reason. The trial which shows no sign of nearing its end.
