Ok, we need a new standard and to see if it can be heard in folk clubs a few years hence.

I'll give it a first verse starter, those of a more eloquent style can chip in.

"Was it written on parchment in days of yore
Or was it just Tin Pan Alley pop hits?
Was it sung by four girls in leotards and glitter
Or a old bloke with trousers up to his tits?"

If you sing it unaccompanied, you can mangle the lines to scan.

The OP of course meant folk club. 99.999% of people realise the term folk is a broader definition than any committee of self appointed hobbyists could ever muster from their narrow experience, especially as the musical genre hadn't really kicked off in popular c20 culture by that point.

PFRis right when he mentions shunned instruments. Cecil Sharpe would have been bemused by the use of melodeon in Morris.

We had a bloke who used to come to a local club to play tunes on his squeeze box (I enjoyed that bit) and to have a pop, loudly and opinionated at anything that didn't fit in his mind box.

Salvation was when he said he would stop coming if anyone played electric. Four people independently of each other brought amps the following week (yours truly played a few jigs & reels on an electric mandolin in a poor attempt to inject irony) and sadly musically but thankfully in terms of the people coming back who he had insulted, the old bugger hasn't been seen or heard since.

Folk clubs can and do thrive. So logically, standards not yet written will carry that mantle in years to come. Yes, I can get nostalgic for older formats and attendances but I have no time whatsoever for fools who claim to know everything but decry what they admit they don't even go to and haven't for many years.
