The 5th Dimension had already found hits with Nyro's "
Stoned Soul Picnic" and "
Sweet Blindness" during 1968. When recording tracks for their upcoming album
The Age of Aquarius, producer
Bones Howe suggested recording another Nyro song. 5th Dimension member
Marilyn McCoo was then engaged to another member of the group,
Billy Davis Jr., though they had not decided on an actual wedding date when the album was released in May 1969. The first single released ahead of the album, "
Aquarius/Let the Sunshine In", was a tremendous hit, while the success of the second single, "
Workin' On a Groovy Thing", was much more modest. When a
disc jockey in
San Diego began playing "Wedding Bell Blues" from the album,
Soul City Records saw the song's potential, and in September 1969 it was released as a single. "Wedding Bell Blues" quickly soared to No. 1 on the
U.S. pop singles chart, spending three weeks there in November, 1969 and made one of the group's somewhat rare appearances on the
U.S. R&B singles chart, where it peaked at No. 23. It was the group's second of five #1 songs on the
U.S. adult contemporary chart. It was a number one pop hit in
Canada and placed in the top 20 on the
UK Singles Chart—and their only hit there except for the earlier "Aquarius/Let the Sunshine In". It became a
platinum record. In 1969 television appearances, McCoo sang lead vocal parts of the song to Davis, who would then respond with quizzical looks. The rest of the 5th Dimension's early hits had featured more ensemble singing, and McCoo's prominent vocal and stage role on "Wedding Bell Blues" might have led to her being more featured in the group's early 1970s productions. ==Morrissey version==
