Robert E. Matonis, better known as Beatle Bob, was an American dancer and a well-known figure in the St. Louis, Missouri music scene. He was known for his arrhythmic dance moves, Beatles-inspired "mop top" hairstyle, and tailored 1960s-style suits. He was often seen doing his characteristic dancing at a wide range of concerts, both in the crowd and onstage with the performers. His constant presence and dancing was welcomed by some concertgoers and an aggravation to others. He allegedly went to at least one live show every night from Christmas Eve 1996, and saw over 10,000 bands.
