I remember Cyril Twney singing "Buttercup Joe" in the back seat of my car while en route to a gig somewhere in darkest Scotland. He also did an "Old Sow" song with all kinds of strange noises.
Cyril's devotion to the tradition was confirmed when he rounded off a gig - the last of a scottish tour, at a rather twee traditional club in Glasgow - by singing "She wears red feathers and a hula-hula skirt"!
God bless you Cyril.
