AVAILABLE SOON: Comely, raspy-voiced vocalist, whose current group is calling it quits, may be willing to consider a supporting role in another musical act. Able to play Florence Ballard to your Diana Ross, Charlie Watts to your Mick Jagger, Flea to your… well, you get the picture. ”Happy just to be here” attitude makes interviews and photo shoots a snap. Other skills: Fleet-footed backup dancing, ability to sing a mean bridge, and inherent bootyliciousness. Am I the girl? Available any time after current world tour wraps in the fall. (Anyone who wishes to supply references — or testimonials about this candidate’s many talents — should post them here.)
