Here is a quick demo.

What I like about the Yamaha style is the drums and bass.. I will remix it and sequence a different guitar part, delete a piano part that just doesn't fit.
I will leave the basic intro /ending in place.

I used the E-A7 for the demo.. with instrument changes..

One other thing I will add a bass line for intro and endings..It is a bit empty without the bass(mostly ending).
