According to this source, the first line is Igbo and means „Take it easy“: <a href="https://www.nairaland.com/261964/nairaland-official-igbo-hausa-yoruba/40" rel="noopener noreferrer" target="_blank">https://www.nairaland.com/261964/nairaland-official-igbo-hausa-yoruba/40</a>;. It starts with „Biko“ though in the song and „biko“ means please in Igbo.

Only the last two lines are Swahili

Karibu kiti- welcome and have a seat

Utapewa nini?-what would you like to be given
