Motown Records' first bona fide female star, Mary Wells enjoyed a string of Top 40 singles between 1962 and 1964, including her signature tune, the coy, soulful No. 1 hit "My Guy." Blessed with a unique singing voice that sounded equally demure and come-hither, Wells helped to usher Motown into the American mainstream during the early 1960s, but like many of its stars, failed to repeat her success once she left the label's aegis. A string of failed record deals and troubled marriages torpedoed her career, and by the early 1970s, she had left the business altogether. Wells mounted a brief comeback in the early 1980s, but found a receptive audience on the nostalgia circuit. As her life appeared to achieve a state of normalcy in the early 1990s, she was diagnosed with cancer, which depleted her health and fortune. A host of famous admirers revived her finances shortly before Wells died from the disease in 1992. Though she had never achieved lasting fame during her lifetime, her music - particularly "My Guy" - enjoyed enduring popularity for nearly half a century.
