They think they have found the missing two-thirds of the original manuscript of the ever-so-popular A-major sonata (one extant sheet is kept in Salzburg).
The find is claimed by Balazs Mikusi, 42, head of the music department of the National Szechenyi Library in Budapest.
Verification will take many months, perhaps years. I shall be in Budapest next week. If time permits, I’ll try to take a peek for curiosity’s sake.
