Found this book with song title listing. If you can't obtain the book, you can copy the song title and paste it into google with 二胡乐谱 after the title and you'll be able to find [most of] the songs to download. I have a jinghu 100 song book but I downloaded all the songs anyway instead of copying the book.
Don't include that ESCS square after the title.
** Per David's request, here's the PinYin/English names for these songs -- don't thank me, thank Google Translate!! Another pdf file.
