Bill,

Greetings from Michigan.

I've done just what you've suggested. I use the arranger for backing and add sax, guitar, and trumpet.

The good players will have no problem because they listen. Some players will struggle. Most band players aren't used to playing with perfect rhythm no matter how good their drummer is. Rhythm wise some will stray a little if they don't listen. If they do, you should be able to pull it off just fine.
