The Hungaroton/CBS recording with Eva Marton and Samuel Ramey (I imagine
that's the one you referred to) gives the tital as "A Ke'kszaka'llu' Herceg
Va'ra" (where the apostrophes indicate accents).  So you just made a small
spelling mistake.  (Or perhaps Hungarians would not consider it a small
mistake!)
