I think you are talking about visual images, not about music itself. For them, it remained only to look after their outfit, appearance and retro styling, because their so-called "music" is horrible. Lucky you never heard such a bullshit. The like things goes on TV, and TV bosses
justify this permanent disgrace by saying "People eat it". Ha-ha, I read that jobs on television stop being prestigious anymore (it was, earlier), and it serves them right.

Those polished swell guys in grey suits from 50s in America and England... they sang sweet though silly songs, stupid though nice, imho.
