Genie, I admit I did not go back through all the posts before making that claim. I was relying on my memory, which I have already admitted is not infallible. Nevertheless I can definitely recall one poster who uses a book who has a repertoire of more than 50 songs. Another justified using a book by saying they would not repeat a song during a year.

However it would be wrong of me to suggest that either of these are poor singers - perhaps they are among those who can sing well from a book. I phrased my original comment poorly - what I should have said is that there are singers who use books who set themselves these targets, and also there are some who admit to being poor singers.
