Do yourself a favor and hit PLAY then close your eyes during the whole video.
This caught me by surprise seeing how a guy, Marcelito Po Moy of Cavite, can sound this good in a girl's voice! If you had your eyes closed, you'd be confused at the fact that we're talking about a guy performing, singing here! Anyway, as you can see, he brutally kills the high notes! He sings 3 songs and nails em all. I applaud how he's very flexible with his voice, even doing better than Regine as she shouts with her already-normalized high-pitched voice IMO LOL. Oh and he's straight.
Thanks Eating Sleep!
