Don’t want to repeat myself, so please read the entire background story on the YouTube page:
Very well done. I can imagine this took a lot of time and effort. congratulations on creating a very cool song and production.
Many thanks for your kind words!
Yes, it took a lot of effort but it couldn’t have been done if I hadn’t kept the original 40-year-old recording.
Wow! Sounds good. Oldies goldies! 
Good enough to say Excellent!
It is very important to have backups today too. Maybe our childs of shilds will do remixes after 40 years
Did you record tracks from old multitrack tapes?
Thank you!
No, I was not able to import any tracks as they were recorded on an 8-track TEAC tape machine (not to be found any more).
But by listening to the stereo mix I was able to re-create the song.
