Justin Vernon and Aaron Dessner teamed up to present the inaugural Eaux Claires Music Festival in Vernon’s home state of Wisconsin that featured a revival of Bon Iver as well as headlining sets from The National, Sufjan Stevens and many other close Bon Iver/National associates. The weekend received rave reviews and the duo is already hard at work on planning the sophomore edition. Or at least, they were until someone broke out the karaoke machine.

This video, courtesy of Aaron Dessner’s Instagram, finds Dessner, Vernon and others in a “super serious Eaux Claires planning meeting” that included some Stevie Wonder karaoke to the tune of “Boogie On Reggae Woman.” As Dessner noted, the meeting “resulted in debilitating hangovers.” Watch below.
