Looking at this promo video it looks to me to be a bit over the top.
A song sung by seventeen people with bodhran and flute etc. Is this how the songs were presented to Marjorie Lansing Porter? The whole promo video is like going back to the 1960's "Folk Scare", New Christy Minstrels and all that dross. I thought that we had left that behind long ago. Folk music for a non folk audience.
