England, 1640s. Civil war and politics interfere with Elvira's plans to marry Arturo, because he is helping Queen Elizabeth escape from the rebels. Elvira doesn't understand any of this, so she goes stark raving mad and sings a cadenza while lying flat on her back, her head hanging upside-down over the edge of the stage. Fearing that she might die of grief or fall over into the orchestra pit, Uncle Giorgio and Riccardo sing the complete version of "Suoni la tromba," including the repeats, and no cuts. Not to be upstaged by any of this, Arturo finally returns from his mission and explains everything by singing a high F above C, the highest note ever composed for tenor voice. There is much rejoicing. It's non-stop, nail-biting action, and Beverly Sills is on hand to provide commentary on the drama.
