El cantante - Ruben Blades

In 1978, Ruben Blades wrote the song "El Cantante"; Colón convinced him to give the song to Colón's former musical partner, Héctor Lavoe, to record, since Lavoe's nickname was already "El Cantante de los Cantantes" ("the singer of singers"). Lavoe recorded it that same year, and it became both a big hit and Lavoe's signature song; a biographical film, El Cantante from Lavoe took the same title. (The film El Cantante told a fictionalized version of this story, in which Blades tells Lavoe he wrote the song for him.)
