What was the Theme song (Title) of the San Miguel Beer Commercial Aired during the 90's.?

I want to know the Theme song (Title) of a San Miguel Beer Commercial aired during the 90's. The message of the commercial is about camaraderie, brotherhood and Filipino hospitality ... There was also a lady in white dress singing on top on a hill on that commercial and she was singing the song I'm looking for... This song has been hunting me for years now and I really would like to know the title of that song... Thanks
