If the roadshow had been in a house, Mphokazi would have brought it down. Children scream and clap, and teachers' eyes well up. Emma Richards afterwards seeks her out to congratulate her. Sky 189 says that when Mphokazi is older she will be "30 times better than me. She's been noticed. People who can make a difference are aware of her."
And what about Mphokazi herself? Is she excited? "I just want to sing. I am going to sing. I want to sing to everybody," she says. Yes, but how will she achieve her goal? The details don't concern her. She shrugs and says, "I will just sing."
Sky 189, 28, who grew up as a graffiti artist in Cape Town and has immersed his life in hip-hop culture, says the roadshows "broaden children's outlook and say you don't have to grow up in a little box".
He adds: "The seeds are planted. We don't know what they will grow into. For some, today will mean absolutely nothing, but to the next person it may make the world of difference."
