Fans of Public Radio International's This American Life have probably known about the December 18, 1998 live show, What Are You Looking At?, ever since it happened. So I suppose I'm mentioning this for They Might Be Giants fans, as the group was present and performing throughout the event (along with the "This American Life Orchestra"). They perform some good short stuff, but also underscore and accompany the essays in the show. Ira Glass talks to and about the band and the music for the show at index 44:50.0.

Though I imagine real TMBG fans knew about this even before the TAL fans...
