Custom arranged for full orchestra feature solo tenor with SATB choir back up and full orchestra See the Sample score for a full list of instruments. The inro uses two acoustic guitars but both parts are cued in the piano part and also included on a synth part and are doubled in two vibraphone parts which could be considered optional. Note that there are many percussion parts, some which could be optional. This is in the key of Cm which is down one step from the original. However this does cause the guitar one part to be retuned. Ask about different key and instrument substitutions.
