"B.Z." is actually [a=Joanne (2)]. Her record company decided it would be more marketable to release "Jackie" as "B.Z. featuring Joanne" (they were right as it turns out, "Jackie" became a huge hit).
"B.Z." is apparently derived from [a=Blue Zone (UK)], the group that originally released "Jackie" in 1988.
(Joanne's second single was also released as "B.Z. featuring Joanne"; while on her third single she was credited as "Joanne B.Z." then dropped the "B.Z." entirely....)
