During the “Dreamboys” concert at the Music Museum on Saturday, July 11, Matteo Guidicelli treated his fans with a surprise number.

His spiel goes: “If I master patience and understanding, I think I’d conquer the whole world. But you know what? If I conquer the whole world, the whole world wouldn’t be complete without—.”

He then performs Sarah Geronimo’s “Kilometro” to the delight of the crowd.
