He lived in Ocean Township and Asbury Park and attended St. Rose High School in Belmar.
Hauser was 14 years old in 1956, when he went to a Frankie Lymon and the Teenagers concert at Convention Hall. The show ended abruptly when fighting broke out, and young Hauser helped Frankie and the Teenagers back to the dressing room. There they serenaded him with an a capella version of “I Promise to Remember.” Inspired, Hauser formed his first singing group, the Criterions, the next year, with friends from Belmar and Neptune.
In 1969 he formed the first version of a much more successful group – the Manhattan Transfer. The group would go on to win 10 Grammy awards and scored many gold and platinum records. They achieved their biggest hit in 1981 with their cover of “The Boy from New York City” when to number 7.
In 1998, the group was voted into the Vocal Group Hall of Fame.
