The English rights to Mach GoGoGo were acquired by syndicator Trans-Lux (originally and still exists as an electronics manufacturer), and Speed Racer premiered on American television in the fall of 1967. In the series, Speed’s full name was Go Mifune, in homage to Japanese film star Toshiro Mifune. His name, Americanized, became Speed Racer. His adventures centered on his powerful Mach 5 car, his girlfriend Trixie, his little brother Spritle Racer, Spritle’s pet chimpanzee Chim-Chim, and his mysterious older brother, Racer X, whose real name was Rex Racer. For American consumption, major editing and dubbing efforts were undertaken by producer Peter Fernandez, who likewise not only wrote and directed the English-language dialogue but also provided the voices of many of the characters, most notably Racer X and Speed Racer himself. Fernandez was also responsible for a rearrangement of the theme song’s melody, written and composed by Nobuyoshi Koshibe, and he subsequently also wrote its English lyrics. The theme was performed, in the opening and closing titles, by Danny Davis and the Nashville Brass; however, Davis and the Nashville Brass were not credited on screen.
