I have NO problem with singers who are breaking in a 'new' song at a singaround having the lyrics handy as an aid . What I DO object to is
singers holding a book like Sing Out between them selves and the audience so that they are singing at the bloody book , not to their audience .
Equally annoying is getting the book out and sorting out the song they want when they should be ready to sing - A REAL waste of time , though riffling through the pages when some one else is singing is NOT polite !
In UK , use of words never used to be at all common , though it is , sadly , a growing trend - something we seem to have borrowed from USA
