The most sensible thing to do is to write to the Greek-Catholic Diocese, Betlen-Utca, Nyiregyhaza, Hungary. The Bishop does not speak English, but his secretary does, and would probably be moved to respond to a courteous letter. Putting something in the envelope could conceivably assist the wheels of progress.
It would be interesting, for purposes of comparison, to obtain a similar recording from the Orthodox in Hungary, who use a different translation and probably also use a different chant system.
Christ is Risen!
