I have an mp3 of the patcher/keygen by Digital Insanity for Sony Vegas in my music collection. Such a banger, even after all those years.
It has been stuck in my head for years and I was able to find it now!

I didn't think many people cracked Vegas back in the day, I needed it for digital media presentations :)
