Bayan Ko – Wikipedia

In February 1987, a cover by pop singer JoAnne Lorenzana was launched as part of a nationalistic campaign by PLDT, and was aired on radio and television for the first anniversary of the Revolution. On 1 August 2009, Bayan Ko was sung as the recessional of the noon Mass at EDSA Shrine, ending the quarant’ore for Corazón Aquino.
