When Battle of the Planets aired in Spain during the 1980s, the series was given a new theme song. This song was titled "Comando G" (As G-Force was renamed 'Commando G' in Spain), and was sung by a kids group named Parchis. Parchis also recorded three other BotP-related songs, though the other three songs were not used in the series. Instead, they were released on a pair of EP records, as well as appearing on various Parchis LP records.
One of these LP records was titled "Comando G," and included both the new theme and a song for Zark titled "Zark-7," as well as songs like Spanish language versions of "Video Killed the Radio Star," "Animals, Animals, Animals," and "Man Gave Names To All the Animals."
Well, the Comando G LP record has finally be released on CD, thanks to a Spanish music comapny named Divucsa. Along with the 10 tracks that were on the original LP, they also added another of the Parchis BotP songs, "La Batalla de los Planetas." The covers for this disc can be found at the Divucsa website at this link.
If you're wondering what the songs sound like, they were included as part of the bonus material on one of the ADV Gatchaman DVDs, or you can see some music videos that the Parchis did for them on YouTube:

Unfortunately, I've been unable to find a place where you can order the CD, though I do know that it can be found on eBay, if you wish to look there.
