Jack Antonoff had some fun on The Late Late Show With James Corden last night, stopping by to perform a song called “Magic Pancakes,” written by 11-year-old Owen Roberts and then put to music by Antonoff, Reggie Watts, and the rest of the Late Late Show Band. The song is concerned with appropriately 11-year-old things, mainly an intense love of pancakes and a rejection of all other foods — totally understandable. A behind-the-scenes clip shows Corden and Antonoff meeting with the young songwriter and exploring the sociopolitical implications of the song. Watch below.
