Cultural Diversity Fair

I have been asked to perform a ballet routine at our town's local cultural diversity fair this Saturday.  The dance is to Carmen Burana: O Fortuna.  I last performed it a year and a pregnancy ago at the Showstopper regional competition, for which I won two awards.  I have 5 days to refresh the routine in my mind and practice, although practice should be interesting since I now have an infant.  If I am lucky I will get one day of practice, the day before.  I have been wanting to get back to my dancing, although I'm not sure if plunging into it without being completely ready is the best idea.
