From the wiki: “‘Wedding Bell Blues’ was written and first recorded by Laura Nyro in 1966 that would go to become a #1 hit for The 5th Dimension in 1969 and, subsequently, a popular phrase in American culture.
“Nyro wrote ‘Wedding Bell Blues’ at the age of 18 as a ‘mini-suite’, conveying the dual themes of adoring love and frustrated lament, and featuring several dramatic rhythmic changes.
“When Nyro first recorded ‘Wedding Bell Blues’ in 1966, she had arranged it in a spare, almost demo-like form*, intending this version to be a part of what would become her More Than a New Discovery album. However, producer Herb Bernstein would not allow Nyro use the arrangement, which ultimately led to her to more or less disown the entire album. What was recorded and released was fairly similar in content and arrangement to the later, much more familiar, 5th Dimension version, albeit with a somewhat more soulful vocal line. Nyro’s album arrangement was released as a Verve/Folkways single in September 1966 but did not chart on the Billboard Hot 100, remaining instead ‘bubbling under’ the Hot 100 – peaking at #103.
