Other audio recordings of "Дорогой длинною":

Bard-Cafe Tsiganskie romansy (No. 3)

Diapasoon home page (No. 7; slow loader)

Song From Collection. Pavel Severov (7th from the top; seems to be a field recording)

I can't read, but something interesting appears to be written in Russian about Mary Hopkin, "Those Were the Days" and the original on THIS PAGE.
