Sheila was the bassist in the London-based rock band, Elastica from 1996 to 1998. Sheila joined the band in early 1996 a year after original bassist Annie Holland left, and Sheila became an especially close collaborator of Donna Matthews during a period when Matthews became a more dominant creative force than bandleader Justine Frischmann. _She_ was asked to leave the group when Frischmann convinced Holland to return in 1998 (which eventually led to Matthews quitting). <sep>, Pronoun: She <sep>, A: Donna Matthews <sep>, B: Justine Frischmann
