Observer -
Today ringbinders, tablets, phones used with the reasoning/excuse of "Oh I only use it as a prompt" - yet time after time after time they sing the same bloody song and yet still they need the "prompt", they still sing to the room head down nose jammed in the ringbinder, tablet, phone.
I see a distinction between a free admission gathering such as a singaround or mixed session where in some cases it might be permissible - occasionally they are just a fairly closed group of friends anyway - and a paid admission event. I really don't want to pay money to hear someone read a song that they have not learned.
