How do I simultaneously left-align and right-align?

I’m making a concert program – where the piece titles appear on the left, the composer’s names appear on the right on the same line, and then beneath that performers are centered in the middle. And that repeats over and over.

Right now I’ve tabbed composers over, but it would look MUCH better right-aligned. Can I do this without creating columns?

Ideally it would be great to know how to do this in Pages, but otherwise in Word.
