Apollo kids all have an obsession with Broadway. If you even say a lyric to a song from it, the Apollo kids who heard will immediately start belting whatever song it's from. For example, if you say 'non-stop' they will start singing 'Non-Stop' from Hamilton at the top of their lungs. The rest of the Apollo kids will starts singing it too. Basically, be careful of what you say around Apollo kids, or you will have Hamilton or Les Miserables being blasted in your ears.
