With this new line-up, they arrived back in Wellington and adopted a new name, Mi-Sex. The name originated from a song they were playing at the time by a British group Ultravox, called "My Sex" To create their new image, they discarded the old attire and on went the leather pants and tank tops. Short hair was also called for to complete the look.

i'd go with "me" but say it FAST!
