The only place I've seen the Byzantine Notation is as the last piece in the "Psalterion Terpnon" from the Monastery of Simonopetra. Since they're the ones who actually put it to music (St. Nektarios wrote the poem), it makes sense. I've never seen it anywhere else in sheet music.
I wish I had a working scanner, because I could scan my photocopy of the original and email it to you. Alas, no scan, so no send.
