So, I've had a few cases similar to this. Old song, unknown tracks, unknown style, can't find the original file to edit it.

Since I really wanted to redo the song, I simply started from scratch. I selected a style that I liked and went from there. As things turned out, the second version was actually much better than the original.

I get the concept of wanting to make the song exactly like it was originally, but try a redo from scratch.
