"It is with a heavy heart and extreme sadness that i inform you of the passing of my dear friend Connie Francis last night," said her copyrights and royalties manager, Ron Roberts, in a post on social media. "I know that Connie would approve that her fans are among the first to learn of this sad news."
"Pretty Little Baby" was released on Francis' 1962 album, Connie Francis Sings "Second Hand Love" & Other Hits, which peaked at No. 111 on what was then known as the Billboard Top LPs chart.
