One of the things I have never understood is how people who don't know a song well enough to sing it without some sort of a prop can possibly enjoy it - surely, the pleasure from singing comes from making it work, for yourself and for the audience.
This, from an extended interview we did with Ewan MacColl over a six month period in 1978 - apologies to those who have read it before.

"Now you might say that working and training to develop your voice to sing Nine Maidens A-milking Did Go or Lord Randall is calculated to destroy your original joy in singing, at least that's the argument that's put to me from time to time, or has been put to me from time to time by singers who should know better.   
The better you can do a thing the more you enjoy it.   Anybody who's ever tried to sing and got up in front of an audience and made a bloody mess of it knows that you're not enjoying it when you're making a balls of it, but you are enjoying it when it's working, when all the things you want to happen are happening.    And that can happen without training, sure it can, but it's hit or miss.   If you're training it can happen more, that's the difference.   It can't happen every time, not with anybody, although your training can stand you in good stead, it's something to fall back on, a technique, you know.   It's something that will at least make sure that you're not absolutely diabolical……………
The objective, really for the singer is to create a situation where when he starts to sing he's no longer worried about technique, he's done all that, and he can give the whole of his or her attention to the song itself, she can give her or he can give his whole attention to the sheer act of enjoying the song."
