You've just contradicted yourself Dick - I didn't feel any need to use words when I started singing in Folk clubs in 1966 but a combination of medical problems and medication has made my memory so unreliable that these days I can rarely get through a full song without use of a prop used ( as I said previously) as discreetly as possible.
For some people it's an age thing -

However I rarely forget an tune - I dont need an instrument to accompany me and I never sing sharp or flat. Yet you are arguing that I should be banned from participating in a hobby I have been pursueing for nearly 50 years

I've never heard such rubbish and the people at Amberley should be ashamed of themselves.
It certainly shows why there are so few folk clubs in the South of England
