Help me choose a song to perform

Hey everyone! I just got asked at my school to perform at a literary evening and I was looking for some advice on what to play. It shouldn't be long since there is a performance I'm doing before this one and I'm looking for some intermediate pieces. I've played a piece like half a year ago at the same event and it was the main theme from Schindler's list. I'm looking for something similar, but any suggestion is appreciated. Thanks!
