I've taught this same version of "Spain" several times now. I use this piece as one of several options when teaching Jazz Standards. I demonstrate several pieces from Brubeck, Gershwin, even other Chick Corea pieces, and let my students choose their own repertoire, but, the kids just love "Spain", and consequently choose it more frequently than other standards. They play it well when they're finished studying it as a result. I like this arrangement myself, and have actually improvised from it in performance!
