He wasn't singing a traditional folk song - (or maybe I missed it)

Ed Sheeran - The Parting Glass

The songs I heard had little, if anything to do with 'folk forms) - not one of them could be described as narrative ot word based

Gallway Girl is a narrative about how he met his love and Nancy Mulligan tells of how his parents met and married despite their liaison being frowned upon.

I am not saying either of them are folk songs. I am saying they are "contemporary songs using folk forms and functions" and that is subjective.

I actually asked you how your attitude towards what takes place in a folk club corresponds with my analysis of what a folk song is

And I have actually answered many times as well. Traditional folk song is taken as read. Traditional folk songs belong in folk clubs. That leaves "contemporary songs using folk forms and functions". Of those I think we agree on the majority. The ones in question are a matter of taste or interpretation.
