Gregorio García Segura (Cartagena, February 13, 1929 – Madrid, December 5, 2003) was a Spanish composer. He studied composition, beginning his studies at the Cartagena Conservatory and continuing them in Madrid. He considered becoming a pianist but ultimately chose to compose songs, film scores, theater scores, and musical revues. He and his brother Alfredo García Segura created numerous pieces, credited to the García Segura Brothers. From the late 1950s, he composed music for nearly two hundred Spanish films, including such famous songs as "Corre, corre caballito" (Run, Run, Little Horse), performed by Marisol. In theater, he worked frequently with the popular Lina Morgan and is the author of, among other works, the well-known song "Gracias por venir" (Thank You for Coming). He also composed music for such popular revues as "Pura, metalúrgica" (1975), "Vaya par de gemelas" (1980), "Hay que decir sí al amor" (1983), "El último tranvía" (1987), and "Celeste no es un color" (1991). The García Segura brothers, with their song "El telegrama" (The Telegram), performed by the Chilean singer Monna Bell, won first prize at the inaugural Benidorm International Song Festival in 1959.
