A harmony quartet offering as wide-ranging a repertoire as their name suggests, coming across like a South African Il Divo and a sleepy Ave Maria. Accompanied by a string quartet, or a township boy band with cheesy moves on some diluted soul pop numbers. With this family friendly variety show, the Soweto Afro Pop Opera has a serious mission: that of culturally bridging Britain and South Africa. A performance showing that Ave Maria is as much a part of South Africa's culture as the Pata Pata. **** (BroadwayBaby.com).
