What does the wind song off of the disney film mighty joe young actually mean?

I have been watching Mighty Joe Young for years and love the wind song I have found several translations online and I am wondering which ones is correct.
Imba limbo
Wa upepo
Wakati unajiwa na
Imba wimbo wa upepo
Wakati ndoto tamu
Lala mpaka usiku uisheni
Upepo wa usiku
Wimbo wanko na
Wimbo wangu inaendelea milele

Thanks :)
