[4] The Human League had recently split acrimoniously over creative differences, leaving only two of the original four members, Oakey and Adrian Wright, to continue.

[citation needed] Without preamble, Oakey asked both girls to join the tour as dancers and incidental vocalists.

[citation needed] Catherall now states that she knew it was a genuine offer, as Oakey was well known in Sheffield; she and Sulley already had tickets to see The Human League on the Doncaster leg of their tour.

[citation needed] Catherall and Sulley agreed to the offer immediately, despite having no singing or professional dancing experience.

This was overturned reluctantly when Oakey, complete with his then trademark lop-sided haircut, red lipstick and high heeled shoes, visited both sets of parents to convince them that the girls would come to no harm.

[6][7] The first European tour of The Human League got underway with the two young recruits assigned to dancing and incidental vocal duties.

Although the tour was a success, the crowds were largely hostile to Catherall and Sulley, as fans had bought tickets for the original all male line-up.

The mid-to-late 1980s were not a particularly happy time for Sulley, as she had to deal with the personal problems unexpected international fame brought her.

Also, internal disputes and pressure to produce more hits caused conflict, and eventually splits, within The Human League.

"[9] In 1990, the band released their last album for Virgin Records, Romantic?, which included the minor hit single "Heart Like a Wheel".

The stylish accompanying video, set in a Parisian café, gave (the now 32-year-old) Sulley the best opportunity to demonstrate her considerable screen presence since "Don't You Want Me".

In 2006, they played to an audience of 18,000 at the Hollywood Bowl, and appeared on the network US television show Jimmy Kimmel Live!.

In a 2007 interview, Sulley stated that the main effort of The Human League in the immediate future was the recording of new material, with the possibility of a new studio album, while continuing to play live at a variety of venues both in the UK and internationally.

[15] Although her birth name is Susan Ann Sulley, she has been known professionally by a number of variants throughout her career; the table below shows the chronology.
