Guys important question... Does anyone know of a music video where groups of people are walking around singing a song and they are trying to steal the lime light from each other. One group has a guy with a rock band guitar and another has a girl dressed as a ladybird(I think). The video ends with the actual band singing and everyone rocking out. Please help?
