Showing their love for Mother Earth through music are (L-R) Zia Quizon, Christian Bautista, Juris, Jed Madela and Kyla.

RnB princess Kyla, who recently married her long-time beau Rich Alvarez, performed in this figure-hugging outfit, squashing pregnancy rumors.

Christian Bautista and Zia Quizon sang "Way Back Into Love" as they sent this message to the public: Go back to the basics; reduce our carbon footprint by walking or biking.

For his solo set, Christian channeled British rock vocalist Bono as he performed a medley of U2's hit songs "Elevation" and "Pride (In The Name Of Love)."

The crowd sang along as Juris performed her famous tearjerker, "'Di Lang Ikaw," theme song from the local remake of Mexicanovela Rubi, which starred Angelica Panganiban.

The famous line from the song, "Hindi lang ikaw ang nahihirapan," embodied Mother Nature's desperate cry for help.
