How Now Brown and the Moo Wave are a Muppet new-wave rock band seen on Sesame Street in Season 16, spoofing on then-current new-wave rock bands. The band's lead singer was How Now Brown (voiced by Christopher Cerf, who also wrote the group's music), whose backup singers were two recurring Muppet cows (voiced by Cheryl Hardwick and Ivy Austin). The other band members were comprised of three Anything Muppets: a Pumpkin keyboardist (who wears a headband with built-in cow horns), a Green drummer, and a Lavender guitarist (both wear matching gold necklaces).
