Hello, artbrooks. I have an album of theirs called 'A Cool Day and Crooked Corn.'   It's been one of our favorites. Years ago I sent a letter to the producer listed on the album, asking for contact info about a possible gig, but nobody ever responded.

I can't remember when that was, but it was before CD's were invented - so possibly the late-medieval period.

Quito, thanks for your attempt, but that Facebook page is no help.   It seems to be images off old albums, none of which I can read.
