* You might have misspelled the name. Are you thinking of a different artist? Could it be Donna Summer, or another artist with a similar-sounding name?
* It's a less-known artist. If this is a more obscure artist, it might be harder to find information about their backup singers.
To help me find the right information, please provide me with any additional details you remember, such as:
* What genre of music did this artist play?
* What was the name of any songs you know by this artist?
* Were they active in a particular decade or period?
Once I have more information, I can try to track down information about their backup singers.
