I find it appalling that singers use word sheets in what they call performance.
What is worse,for me,is when these singers repeat the same song,maybe in multiples,over periods of time and are still using the words,making no attempt at learning.Reading words as one sings is academia,not singing.
Even worse and in fact stunningly amazing is the people who can not present a song with any form or structure or continuity even though they are using word sheets.These people have no right to lead a song in this way and comperes should not accept them.
Tolerance is the home of degraded standards.
