The Tempest Vocal Score?

Hey there!

I belong to a locals players guild and we have yearly performances in October.

This year I am playing the part of Ariel in Shakespeare's The Tempest. I am having problems making appropriate tunes to the songs the the pleyful sprite is required to sing.

I was wondering if anyone here could lead me to a website or a place that I would be able to get a copy of the vocal scores of the tempest?

Any help would be much appreciated, Thanks so much!
