The theme song was based from the Metro Pop entry “This Guy’s In Love With You, Pare!” sung by the band Parokya ni Edgar which won Best Novelty Recording in the 2003 Awit Awards.
The music video features Vice Ganda, Toni Gonzaga and Luis Manzano performing the song and some scenes from the movie. The lyrics of the theme song was a little bit tweaked to incorporate the “Mare” and the music has a hint of Carly Rae Jaepsen‘s “Call Me Maybe.”
Directed by Wenn Deramas, “This Guy’s In Love With U, Mare!” opens in theaters today, October 10!
