Who are you going to obtain permission from?

There's a curious (and, I suspect deliberate and mischievous) misapprehension here - that somewhere there are 'Guardians of Tradition' or (dare I invoke them?) 'Folk Police' who will come down hard on, and punish, anyone who departs from certain inviolable rules. This is, of course, rubbish!

A singer must make his/her own aesthetic choices - and then Will Fly's inherited family saying comes into play, i.e. "Have what you will - and pay for it".

Thanks, Will - that's a very useful phrase!
