Mozambique is something of an anomaly in terms of Commonwealth membership. It only became a member in 1995 and was never under British control. Instead the country was ruled by Portugal from 1505 until independence in 1975. As a result Portuguese remains the official language and strong ties remain between Mozambique and Portugal. Swimmer Jessica Teixeira Vieira is part of that story, having been raised on the island and has chosen to represent them at events such as the Olympics. Her chosen piece of music is a Marrabenta a musical form typical of Mozambique, and the song is A Nkama wa hi Siya sung by Mingas.
