Samantha was in band named SOX for the Eurovision Song Contest.  It
was an all girl trio (Samantha Fox, Cris Bonnachi, Laurraine MacIntosh).

That was a one time thing though.  Here is a brief summary of them:

"Cris Bonnachi"
    Still a member of Sam's touring band.  She was born in Australia
    and learned to play the guitar when she was 14 yrs old.  She was
    a member of the all women Heavy Metal band Girscholl and session
    musicians of singers like Marc Almond, KD Lang and Suzanne Vega.

    Now she is Sam's best friend.  Both Cris and Samantha are the
    songwriter/producer team for most of Sam's new songs.

"Laurraine Macintosh"
    Still a member of Sam's touring band.  Laurraine is the baching
    vocal singer now.
