The recent tragedy at Cafe Racer struck at the heart of a wild world of artists—musicians, singers, circus performers, new vaudevillians, burlesque dancers, jug bands—that found a home at the cafe. Tonight’s beauty of a show, subtitled “A Concert, Sing-Along, and Celebration of the Lives of Our Dearly Departed,” features a ton of them—including members of Circus Contraption, God’s Favorite Beefcake, and Orkestar Zirkonium, along with the Can Can Castaways, Fuchsia Foxx, Vince Mira, the Bad Things, and more—with proceeds going to victims and their families.
