playing with sanshin

Dear all,

I recently encountered a group of people playing sanshin ("daddy" of the shamisen) in the tradition of Okinawa.

Those people and friends of mine playing shakuhachi would like to play together... but we don't know what...

are you aware of some songs that can be played with sanshins and shakuhachi? and also where to find the scores?

thanks for your help!

cheers
