Constancio de Guzman
He studied piano and composition under Nicanor abelardo, but his father sent him to law school, but he switched to commerce and finished business administration in 1931. After he took the CPA board exams, he started working in the movies. His 'accidental' hit, Panaginip, paved the way for him to record hundreds of songs, principally under Villar Records and Columbia Records. Some of De Guzman's notable compositions are: Bayan Ko, Babalik Ka Rin, Ang Tangi Kong Pag-ibig, Birheng Walang Dambana, and Maalaala Mo Kaya.
