Back on thread though, it was common practice at the beginning for 'Squins', and still is sometimes, for MJ to be going on in the middle of the dance floor when Bobgadget put on a fast enough foxtrot track. This can be ok towards the end of the evening, when the floor is clearing as people go home, but can be a real pain earlier on when the floor is packed, since those dancers who are trying to actually dance the foxtrot (which is after all why we're there in the first place, to do ballroom, right?) have to work even harder to achieve 'floorcraft' (otherwise known as not crashing/treading on people).
Oh, and hands up as one guilty of practising cha-cha (and for that matter foxtrot) at a Ceroc night
yes I know I'm a hypocrite
