Bronski Beat , The Housemartin's , Fun Boy Three, Madness,
EMF ,Se7en (yes really) Boy Zone Depeche Mode, Slik , Ultravox, Culture Club, The Equals, the Dave Clarke Five, The Beatles. Just a few to to start you off .:-D
Actually that Shane Lynch thing is a good bit of trivia. How about this question: Which boyband member had sisters in the groups Fab!, Buffalo G and B*Witched? Put them in that order as well, so that people will be puzzling a little over the first two and then have an "ah, I've got it!" moment when B*Witched are mentioned. That's one of the little tricks of setting a good quiz.
