Last night on American Idol, Candice Glover gave what I called on Twitter “one of the most astounding performances I have seen in a lifetime.” When she took to the stage to sing The Cure’s “Lovesong,” she brought me to tears, and she brought me to my knees. My husband came home while I was watching it for the fourth time. Tears were streaming down my face. He asked why I was crying. I answered, using words that were clearly inadequate to the occasion, “It’s just so moving.” He laughed. I have to admit it was funny, the childlike wonder with which I tried to explain what cannot be explained. I didn’t try again. I just sat him down and rolled tape.
