the song starts with a male person singing:
La La La,
La La La La La Lah,
Lahhh La La La La La Lalala
….
i think then repeating some of the las, after that
electronic synt music is starting.

another part the guy is singing something like:
dab dubndu dab…

if someone would know what my lala means… it would be so great. i was really young as i was listening to this song 🙂
