Maria Callas's Unconventional Opera Performance - Apparently.
Maria Callas, one of the most renowned opera singers of all time, had a performance cut short due to a sudden rainstorm in 1958. During a production of "Tosca" at La Scala in Milan, Italy, the rain caused the roof of the opera house to leak onto the stage, forcing the performance to be interrupted. The concert was eventually postponed, but the incident became a memorable anecdote in the singer's illustrious career.
