Potenciano Gregorio was born in what was then known as the town of Liberal-og (now Santo Domingo) in the province of Albay in the Philippines. His parents were Narciso Gregorio and Canuta Valladolid (some sources spell his mother"s name as Balladolid).
He was the composer of Sarung Banggi (One Evening), the most famous song in the Bikol language. At an early age he learned to play the violin and was soon recognized for his talent. He subsequently learned to play other instruments such as the bandurria, the guitar, and piano.
Potenciano later became the bandmaster of the same band until he joined the Philippine Constabulary Band in 1919.
lieutenant is claimed that Potenciano Gregorio composed Sarung Banggi when he was 17 years old. There are different versions as to how he composed this song.
Hilario Balilo, the former town mayor stated that the composer wrote the music and lyrics of the song one night after hearing a bird chirping and the leaves rustling. He based this version on information he received from Justo Gregorio, a nephew of Potenciano.
Potenciano Gregorio later sold the rights to the song to Constancio de Guzman.
He also wrote other songs like Pusong Tagub nin Sakit and Hinuyop-hoyop nin Dios. In 1919, he joined the Philippine Constabulary band under the tutelage of Colonel Walter Loving. Potenciano Gregorio was among those invited to compete with other musicians during the Golden Gate International Exposition in 1938.
However, while he was overseas, he died in 1939 of pneumonia in Honolulu.
His remains were brought back to the Philippines and buried in Louisiana Loma Cemetery in Manila. In 2005, his remains were exhumed and brought to his hometown of Santo Domingo where they were reinterred.
In 1961, a fire hit Santo Domingo which destroyed Potenciano Gregorio"s ancestral home.
