Look Mum No Computer performs with dancers wearing computer-style costumes, according to reports from UK and Northern Ireland outlets. Both sources describe the act taking part in a stage rehearsal ahead of a competition appearance, with the UK report specifying the group is at a semi-final rehearsal. The coverage focuses on the performance staging and the involvement of dancers dressed to reflect a computing theme, rather than on any changes to the act or competition results. While details beyond the rehearsal setting are limited in the provided excerpts, the accounts are consistent in describing the same visual element: dancers integrated into the performance and dressed in costumes that reference computers. The information indicates the act is in the run-up to live competition programming, where it prepares on stage with choreography alongside the performers. Overall, the reporting aligns on the rehearsal context and the presentation featuring computer-themed dance costumes.
