When Blaine's former love, Ilsa (Ingrid Bergman), first enters his Café Americain, she spots Sam, the piano player (Dooley Wilson), and asks him to "Play it once, Sam, for old times' sake." When he feigns ignorance, she persists, "Play it, Sam. Play 'As Time Goes By.'" Later that night, alone with Sam, Rick demands, "You played it for her — you can play it for me." Sam once again resists, prompting Blaine to shout: "If she can stand it, I can! Play it!"
