60's Soul Shuffle and Peace Ballad. Do they evoke any covers that you can think of?

I think I'll hold off on these, because they probably won't sound nearly as good on Yamaha's that don't have the T4's choir voices.

At Yamaha Music Soft, if you select an S910 as your keyboard, they still demo the T4 version of the style they're selling so you can't really know exactly what you're getting.
