In Ms. Stevens’s 351 regular appearances at the Met, her professionalism was perhaps never more apparent than it was in one of her many productions of “Samson et Dalila.” Playing the temptress Delilah, Ms. Stevens reclined on a chaise longue to sing the aria “Mon coeur s’ouvre à ta voix,” among the most famous seductions in opera. One night, overcome with theatrical passion, Samson flung himself onto her mid-aria.
Samson did not know his own strength. Under his considerable force, the chaise longue, on casters, began to move. Ms. Stevens sailed offstage and into the wings, still singing.
