You might consider bringing a relatively inexpensive guitar for those parts. Please bring your own slides. The stage and audience parts call for capos, but those chords can simply be played with the bar finger. Everyone should bring a wire music stand, a pencil, and a footstool or alternative seating device. Teachers should distribute the parts evenly among your students, so if you're bringing seven students, one should play each part.
Individuals working alone can select any of the parts to prepare.
