I was around in the 60s 70s on the mainstream Hull folkscene and none of this, names or any of it is familiar. There were though lots of strange comings and goings in the surrounding countryside and this group may have been part of that set up. If they were part of the Hull scene in any way I would also be interested as we're currently compiling an Archive of the Hull folk scene. Have a look at our page on Facebook for further info.
