But, just like the songwriter, is definitely not a native English speaker.

Score
The original incidental music was composed by Yuji Ohno, while the English-dubbed version had a new soundtrack composed by Mark Mercury. Mercury's work survived on the Latin American version, but a new opening was added for it, composed by Shuki Levy and sung by Chilean performer Juan Guillermo Aguirre (a.k.a. "Capitán Memo").

For the German version, a completely new soundtrack was created by German composer Christian Bruhn. To this day, the futuristic synth disco funk soundtrack is considered cult for giving the series the right feeling. A soundtrack CD was released in 1995. A remix of the theme Feinde greifen an ("enemies attack") by German DJ Phil Fuldner, called "The Final," entered the top ten of the German and Austrian single charts in 1998.

The French theme song for Captain Future is a song with lyrics written by Roger Dumas and music by Jean-Jacques Debout, performed by Richard Simon in 1981.
In 1987, during its rebroadcast on Club Dorothée, Bernard Minet performed a new song composed by Jean-François Porry and Gérard Salesses. In 2002, Chantal Goya, Jean-Jacques Debout's wife, covered the original song in a dance version.
