What would be a good hip hop / rap song to perform at a school concert?

I'm a Primary school teacher looking to do something a bit different for a verse speaking competition. I'm trying to engage the kids by going outside of the norm but all the songs that they've suggested to me are unsuitable due to content or language - it's not the genre I know the most about so I was hoping to get some ideas for songs that I could adapt for verse speaking. Thanks!
