Swing Out Sister
Original member Jackson left the group during the making of the second album, "Kaleidoscope World". Although the liner notes give "special thanks to Martin Jackson" and his co-writing credits appear on the songs "Tainted" and "Between Strangers", they also point out that "Swing Out Sister are Corinne Drewery and Andy Connell." Drewery and Connell have been the core on all subsequent albums. After leaving Swing Out Sister, Jackson later worked for Frank Zappa.
