Help needed in translating swahili text :-) Thanx in advance!

[Sirenot]

Hi all :-) We are an Israeli all-women classical singers ensemble called "Sirenot" (Tranlates as "Sirens").
About 2 years ago we had the priviledge of meeting a fabulous Tanzanian choir who taught us the folk song "Harambee". We have a recording, we transcripted the words - but we have no idea what the text means
We are looking for someone who speaks Swahili and can translate the text for us 
Anyone up for the challenge?
Below is the text we transcripted, please forgive any mistakes.
Any help would be HIGHLY appreciated
Thanx!!!

O mama geni o
Si we zi ku se ma
Na mwe ne we yu po


Mombasa sie li te na
Una dogo dogo ningi

Muyu ango ani tu ma ve ma
Mi we wana chama wada ima
Si ta we za kuli acha rumba
Mila mono kuli tu ma

Harambee (or maybe "Arambe"?) x 3
Tu a chez e rumba
 

[amf]

O mama geni O           
Siwezi kusema
Na mwenye yupo

Mombasa siendi tena
Una dogo dogo nyingi

Moyo wangu unituma vema
Mi we wana chama wada ima ??
Sita weza kuliacha rumba
Mila mono kuli tuma ??

Harambee x 3
Tu cheze rumba

O mama Jenny o
O Jenny's mother..

Siwezi kusema
I cannot say.. or I have no say

Na mwenyewe yupo
while the owner exists .. while the owner is still around.


Mombasa siendi tena
I am not going to Mombasa again

Kuna dogo dogo nyingi
there are very many young girls there


Moyo wango wani tuma vyema
My heart strongly sends me..

Niwe mwana chama wa daima
to become a life member..

Si ta we za kuliacha rumba
So I can not leave the Rumba

Bila moyo kunituma
without my heart saying so

Harambee x 3
[This is a call used in East Africa(kenya) to bring people together]

Tu cheze rumba
Lets dance the rumba

I have tried my best as far as I remember the song. But its a long time since I heard it so E&OE.
