MANILA, Philippines (AP) - Coldplay's lead vocalist has visited a cancer-stricken fan hours before the group's packed concert at Manila's seaside Mall of Asia Arena Concert Grounds.

Chris Martin visited Ken Valiant Santiago in a hospital where the university student is battling cancer and spends much of the time listening to his favorite Coldplay songs. Concert organizer Rhiza Pascua tweeted a picture of the meeting.

Santiago' brother, Kheil, earlier posted an appeal on Facebook for help in relaying a request to the popular band to say hello or send a short message to his brother, who bought a ticket but could not make it to the concert.
