Filthy Frank's Kenyan song meaning

That is a 1 hour loop from a video on Filthy Frank’s channel on how to pick up women in different cultures. That was one of his earlier videos, so when his channel blew up loop videos came out, but the original song was never found…
Today I did some internet searching to find this song, and found this video.

However, I could not find the original, so I just typed the alleged lyrics(ono omwana atuzaalidwa, omulenzi atuweleddwa) on the detect language part on Google Translate and I got this.
