I heard this song in cinema before the ads and I can't find it online.
This whole thing was sung a'capella so no instruments in there. The background sounded like this
https://vocaroo.com/AK5eNrUgnGSsomething like "chakalaka boom" or "chocolate boom" or anything like this.
I tried looking it by lyrics but it didn't help at all so perhaps I heard them wrong. I think I heard "What is it all about" in the beginning. Maybe this was some local, original song. I don't know.
