Containuity mix-up

In the film there is a mention that each band performing at the Jools Hallond TV show had to perform with the full complete original lineup but when the Human Leauge perform its not the original lineup as the 2 girls in that band are not part of the original lineup. The original lineup of the Human League was an all male lineup. Then 2 members left to form Heven 17 so they decided to get the 2 gigs into the band.
