End music on YouTube!
I just found the end music, along with a video clip, for "The Crazy Family" on YouTube, at:
I've been looking for this music for two decades! As I said in my comment there, I was a bit disappointed at first, not hearing the entire soundtrack before the end theme, but it gets better and better each time I listen to it. Enjoy! Maybe someone will finally put "Gyakufunsha kazoku" on an English-subtitled DVD and publish the entire soundtrack!
Merci bien to the person who posted it there!
