Regine Velasquez and Apl d.Ap Guest in Alicia Key's Manila Concert

It was a pleasant surprise for many Filipino fans of Alicia Keys when local nightingale Regine Velasquez joined Alicia Keys in a duet of If I Ain't Got You.  Regine really hit all the high notes while Alicia did the second voice for the same song!  It was such a rousing number, I actually stood up in standing ovation after they did it.

After that, Alicia, segued into Where Is the Love, where Apl d.Ap of The Black Eyed Peas then came onstage, which again, got the crowd roaring!  The appearance of those two came as Alicia dedicated some of the songs to the victims of typhoon Yolanda.  She really sounded sincere with her comments, which endeared her more to her fans.

Here's the video of that great duet!
