The crowd then sang along with David's hits "The Last Song I'll Write For You (2012)," "Paper Heart (2011)," and "Come Back To Me (2012)."

His latest single, "The Last Song I'll Write For You," was released May this year.

He continued: "This is far removed from our last show in Manila. Any time anyone asks me about what's your favorite show you've done, I always tell this story. Forgive me, it's a bit long.

"So, I always say, we went off to Manila, the Philippines. And what I see is this amazing view...looked out over roughly a hundred thousand people and I thought, wow, half-way around the world to a place I've never been before and all these people are singing my songs back to me, very strange. So, thank you for that!"

For the encore, he performed his unexpected hit revival, "Always Be My Baby."

Then to the crowd's surprise, our very own "Pop Rock Princess" Yeng Constantino emerged from backstage and sang a duet with him. After a great performance, David was all praise for Yeng. "Wow! What a voice. I wish I could sing that well."
