Yoyo, I've been trying to find the Instrumental/Karaoke version of Heats, the second opening of Getter Robo Armrmageddon for a while, but I've had no luck.
I know it must exist because this mashup uses it - https://www.youtube.com/watch?v=eJUNO1k6cME - but I've found sod all anywhere else.
Here's the original song for reference https://www.youtube.com/watch?v=qaJw6lqGFew
It would be grand if you could find it or point me in the right director, but no worries if you can't. Cheers!
