"then quality needs to be encouraged and the unaccompanied word sheet holder is not the way to do iT"
TRUE,unless prformers have practised with their sheets, and know what they intend to do before they get up, for example a good actor would be able to perform with word sheets, because he is experienced and practised at performing with them. the truth is.. it can be done but rarely is because frequently performers use it as an excuse to be unrehearsed.
