According to the Billboard Book of Number One Hits by Fred Bronson,
Brenda Lee recorded this song early in 1960 but Decca Records, held
it from release for several months out of concern that a 15-year-old girl
was not mature enough to sing about unrequited love. When the song
was finally released, it became a smash hit.
J.Cool here and this is true, I swear! In 1959 while in Paris, France, a story appeared in French newspapers proclaiming Brenda to be a 32 year old midget. Really, I am not kidding you! This however had nothing to do with her nickname, “Little Miss Dynamite”
