Did you click on the link in that post … ? It’s right at the bottom of that page. Try clicking on the link in the first post of this thread, and let me know if you can’t find it.
If you click on that link, you should see a page titled “My Sheet Music,” and then see four things below it:
Vaga Luna
Bleak Midwinter
Zdes’ Khorosho
Theme from Piano Sonata #2
If you click on the dark teal-colored names of the pieces, you should go right to a PDF of the sheet music.
