Query: Belcanto at its very best!

If this recording were uncut it would be heaven... But at this time it was a miracle that this rarity was performed at all, because Callas requested it. Callas sings a fantastic Anne, Simionato is the best Giovanna and Rossi-Lemeni has much authority as Henry VIII. This is still the greatest "Anna Bolena".
