Dion & the Belmonts was a leading American vocal group of the late 1950s. The group formed when Dion DiMucci joined The Belmonts - Carlo Mastrangelo (October 5, 1937 – April 4, 2016), Fred Milano (August 22, 1939 - January 1, 2012), and Angelo D'Aleo - in late 1957. After an unsuccessful first single, the group were signed to Laurie Records. Their breakthrough came when "I Wonder Why" made # 22 on the Billboard Hot 100 chart, and the group appeared for the first time on the Dick Clark TV show. Read more on Last.fm
