Megastar Sharon Cuneta and Concert King Martin Nievera rarely sing together to perform live for a big crowd.

But they just did that for their Once In A Lifetime concert held last Saturday, February 11, at the Smart-Araneta Coliseum in Cubao, Quezon City.

VOCAL SOULMATES. The concert, directed by Rowell Santiago with Louie Ocampo as musical director, lasted for three hours.

Sharon and Martin, who call each other "vocal soulmates," proved that their tandem click superbly.

Before they appeared on stage, an audio-visual presentation (AVP) of the two superstar singers rehearsing for the concert and talking about each other was shown on the big screen.

Then, Martin and Sharon opened the concert with a medley of "The Promise (I'll Never Say Goodbye)," "The Last Time I Felt Like This," and "Sweet Love."

After their duet, the two talked about their past relationships.

While remembering the happy and sad memories of their relationships through song after song, an AVP—showing Sharon's old pictures with ex-husband Gabby Concepcion and Martin Nievera's with ex-wife Pops Fernandez—was shown on the big screen.

Martin's high energy and sense of humor became a perfect balance to Sharon's more personal and demure spiels.

At one point, the Concert King referred to Sharon's husband, Senator Francis "Kiko" Pangilinan, as "your soy sauce, your Kiko-man," to which Sharon agreed, "Yes, he's my toyo."

SOLO ACTS. After their first duet, Sharon left Martin for his solo numbers.

The Concert King sang and danced to the tune of "Give Me Everything Tonight," "Moves Like Jagger," and "Party Rock Anthem"—backed up by the G-Force dancers.

After Martin's first solo set, it was the Megastar's turn to wow the audience.

Sharon performed her own renditions of Adele hits "Someone Like You" and "Rolling in the Deep," with a twist of club or disco mood.

"Wow! Nakapag-Adele ako! Ang galing!" she said, all bubbly.
