"A Teenager in Love"
  
is a song written by Doc Pomus and partner Mort
Shuman and originally sung by Dion and the Belmonts,
released in March 1959. It reached #5 on the Billboard
pop charts.
   In May 1959 Dion and the Belmonts was a leading
American vocal group of the late 1950s. The group
formed when Dion DiMucci joined The Belmonts - Carlo
Mastrangelo, Freddie Milano, and Angelo D'Aleo - in late
1957.
   Success won Dion and the Belmonts their first major
tour in late 1958, with The Coasters, Buddy Holly and
Bobby Darin, and this was followed up by the "Winter
Dance Party" tour with Holly, Ritchie Valens and The Big
Bopper. On 2 February 1959, after playing at the Surf
Ballroom, Dion decided that he could not afford the $36
cost of a flight to the next venue. The plane crashed;
Holly, Valens, The Big Bopper, and the pilot were killed
on 3 February 1959, shortly after midnight.
