A song that I sing regularly at the sessions is "The Mingulay Boat Song". Iuse the same tune for the chorus as for the verse,because I like it that way,but there is one particular person,if present will wave his head and grin like a Cheshire cat.He does this because he knows that I know that he knows a different tune to the chorus.GGGGGRRRRRRRRRRRRRRRRRRRRRRRR! That makes me mad.
