I also forgot to mention that if the show gets started on time and the bands run on schedule, the Maidens should be on earlier than usual (i.e. before midnight). I know that DOD usually only does sets of about 30 minutes and if they start at 10:15, the latest that the girls should be onstage is by 11:30.
However, this is just an estimate and things are subject to change in real life conditions so don't blame me if things don't go exactly as I said.
