Here is what Google says about the lyrics of Asimbonanga:

Asimbonanga (We have not seen him)
Asimbonang' uMandela thina (We have not seen Mandela)
Laph'ekhona (In the place where he is)
Laph'ehleli khona (In the place where he is kept)

Oh the sea is cold and the sky is grey
Look across the Island into the Bay
We are all islands till comes the day
We cross the burning water

Chorus....

A seagull wings across the sea
Broken silence is what I dream
Who has the words to close the distance
Between you and me

Chorus....

Steve Biko, Victoria Mxenge

Asimbonanga
Asimbonang 'umfowethu thina (we have not seen our brother)
Laph'ekhona (In the place where he is)
Laph'wafela khona (In the place where he died)
Hey wena (Hey you!)
Hey wena nawe (Hey you and you as well)
Siyofika nini la' siyakhona (When will we arrive at our destination)
