From the wiki: “‘Oh No Not My Baby’ was written by Gerry Goffin and Carole King. The first recorded version of the song was by The Shirelles, with the group’s members alternating leads – an approach that ultimately rendered the song unreleasable because it was a great departure from the Shirelle’s ‘standard’ sound. It would not be released until appearing on the compilation Shirelles: Lost and Found in 1994.
“Maxine Brown recalls, then, that Stan Greenberg, Scepter Records executive, gave her the song with the advisement that she had to ‘find the original melody’ from the recording by The Shirelles: ‘They [had gone] so far off by each [group member] taking their own lead, no one knew any more where the real melody stood.’
