Shimrod, in one mostly instrumental Irish session I used to go to, we had someone quite capable of a longer Tam Lin. I got on well with the person but I'd never be convinced something like that was the right song for the occasion,

In maybe mean and unfair mode, I've sometimes felt the only good Bob Dylan song is the one written by Eric Bogle...

I suspect many of us do have our own loves and pet hates and I for one do not really fit the "broad folky mould" (ie. everything that may get defined as folk does not necessarily follow my own musical tastes). I'd probably in some instances be easier if people went a step further and did a Beatles song or even an acoustic Slade song than some of the stuff that lurks in the middle "acoustic" territory but that's just me...

... and if we are talking in terms of a club offering a mixture, I can pretty much always ride through the bits I personally may not enjoy so much.
