"Anybody can sit behind a piano and sing live"

Um, what?! Sitting behind a piano and singing live, while you're playing is not something that "anybody" can do. I can't believe someone would be shallow enough to even say that. "Intense choreography" in place of live singing is usually something that pop stars do as a crutch to cover up for their limited ability to sing and play instruments. Anyone who had the talent to sing and play the piano exceptionally well would NOT trade that for military choreography, pyrotechnics and other on stage distractions.
