I tardily understand that just yesterday the Berlin Deutsche Oper has staged the last of no less than 13 performances of "Cenerentola" (Venezia, 1900), the first opera of W-F. In Berlin they have presented the opera (I suppose in a German translation) as an opera aimed to a chidren's audience (like often Humperdinck's Handel und Gretel).
Scant Wolf-Ferrari I see elsewhere; just in February 2014 eight performances of the much later (1936) "Il campiello" in Venice and the near Rovigo (same production).
