Are there any Prince sheet music for Housequake, Rock hard in a funky place for alto sax or anything of that nature?

Well, I found this site via google for you if it's any help (make sure you scan/screen any downloads for any viruses though before opening them on your computer just to be on the safe side)

Otherwise maybe eBay?

Anyway, hope this helps.
