“Crazy” by Gnarls Barkley is a very popular song and many people have performed covers of it since it was released in 2006 but this one might be my favorite. Singers Hannah Gill and Casey Abrams join Postmodern Jukebox as they perform their cover of “Crazy” that I enjoyed listening to. If you enjoyed this music video you might also like to watch Puddles The Clown perform a cover of the song “Royals” by Lorde.
