"I think any Folksong Singer - great & small - invents their own fantasy world anyway, just any model railway enthusiast does."

Again the capitalisation....

I sing folk songs, and would fall into the "small" category rather than the "great", but I certainly don't invent any fantasy worlds, whether my own or anybody else's.

Is that because I am not a "Folksong Singer" - just a "folk singer" or alternatively a "singer of folk songs"?
