In a folk club, I did once, just out of mischief, start to sing "As I walked out on a bright May Morning" singing unaccompanied, but after one verse (slightly altered lyrics) went into Dolly Parton's "Jolene" (with guitar).
I think I did an Otis Redding song after that.
It was a small protest against a succession of badly sung, snails pace, renditions of the usual suspects in boring ballads.
The result?
Faces like thunder from the Traddie clique. Enthusiastic applause from the people who like to be entertained.
Country music fans would know that anyone who uses the phrase 'Country and Western' to refer to a single genre, knows very little about it.
I find that the three-to-one rule applies, as in all types of music. There are three poor, or at best, mediocre songs for every good one.
I enjoy hearing a good song, whatever the genre, whatever the context.
Play mediocre ones, whether Trad Folk or Country (or even Western!) and I'm bored and looking for something to liven the place up!

Cheers
Dave
