Mema and Tupe sing their own arrangement of the old Samoan folk song "Sou Fuga Sina"
Sou Fuga Sina also known as Soufuna Sina is a song based on a legend told many times through Fagogo, which acts as a reminder of the relationship that a Samoan brother has with his sister (Feagaiaga - Covenant).
The song explains the desire of the young Sina to obtain the Gogosina bird as her husband. Her 10 older brothers all named Tui go out in search of the Gogosina to fulfill the wish of their feagaiga and as they leave they tell her not to call for them no matter how long they're gone for.
She waits as long as she can and then calls for them but this gives away her whereabouts and the "sauai" Tui o le Tafue now knows where she is, comes to the fale and holds her captive.
When the ten brothers return they see Tui o le Tafue sleeping in the fale and are afraid because he is a supernatural being. The brothers all decide to run away except the youngest who decides to honor his brotherly duty to his feagaiga.
He goes in to the fale and ties Tui o le Tafue's hair to the posts of the fale. They all escape and when Tui o le Tafue wakes up he notices Sina is not with him anymore and pulls the whole fale down and in doing so kills himself.
The old Samoan saying goes
"O le i'oimata o le tama Samoa lana tuafafine" - Every Samoan boy should treat and protect his sister like the iris of his eye.
