The Ratburn Rats
No-nonsense schoolteacher Mr. Ratburn used to lead this New Wave trio on lead guitar and vocals.
From the "The Buster Report" episode (11 October 2010) of animated PBS TV series Arthur.
A flyer and a brief video clip of them singing "I'm a Sewer Rat" is shown, much to Mr. Ratburn's embarrassment.
Mr. Ratburn later formed a band with his fellow teachers.
