A museum director does all sorts of things to support art and artists. At the opening of 'sleepwalkers' the other night, Brazilian musician, composer, and actor Seu Jorge's hands were cold. So MoMA's director, Glenn Lowry, lent him his gloves. When the party moved inside, Mr. Jorge made a beeline to Mr. Lowry to return them. By the time he performed in the lobby for an audience of a thousand, he was on fire. See more photos in the Out & About photo gallery.
