I'd partly go along with Banjer's thesis that "if you've lived 'em, you can sing 'em..." except that it leaves out of account the fact that some people sing better than others, and some people can't sing at all. Perhaps it might be more accurate to say "if you haven't lived 'em, you can't sing 'em..."And I have no problem with Frankham's list.
But just because one bunch of white boys wants to book another bunch of white boys to play at festivals for other white boys, this does not necessarily prove anything.
