Screenshot: The Tonight Show Starring Jimmy Fallon Last week, Michelle Zauner announced that Japanese Breakfast was finally “Jimmy Fallon Big!” enough that her band had been booked to play on last night’s The Tonight Show Starring Jimmy Fallon. Now, the sideways prophecy of the song’s title has been fulfilled: Japanese Breakfast has played “Jimmy Fallon Big!” on Jimmy Fallon. In his introduction to the performance, Fallon explains the track’s genesis, summarizing how the bassist in Zauner’s previous group, Little Big League, left to play in a band that he thought would go on to become “Jimmy Fallon big.” Years later, he returned and ended up in Japanese Breakfast, which now, unlike his other band, are actually, very literally “Jimmy Fallon Big.”
