As a person who has been interested in Folk Music for a great number of years both listening and also performing on a semi professional basis i find it strange that some people who perform do not learn the words. I cannot see how you can give a true picture of your performing ability when doing this. I know that when i started singing i always learnt the song and i did not know any other way. I realise that when starting out it is a very nervous experience, and having the words with you is a great safety net When i used to practice a song i used to not only do it at home but when walking to work and also going to the shops. I also think that people who go to folk clubs and sing with words might just need a bit of encouragement from other club members and the organiser to release the talent that is there but needs to come out more fully.
