Until last week fourth impact always managed to sing one of their songs from their established repertoire, polished over years. They didn't want to sing 'shut up and dance' which was suggested for the sit week, and went back to a safe, already practised song. This week they had to take on a new song, having to remember the English as well as new harmonies and dances, and it showed, hence they did t seem so good.. They work hard, but a few days is not enough to polish to their previous standard. I wonder whether the producers anticipated this, and will let them have their own way with song choice, or push them out of their comfort zone with new material. Especially if they reach the later stages where they have too prepare kore than one song.. Will they become 'difficult to work with?'
