I was convinced that the hymn 'Lord of the Dance' contained the lyrics 'Don Sept, whoever he may be, I am the Lord of the Dance said he' and pictured a Pied Piper type character leading children dancing all over the hills as he played a recorder. This persisted until I reached the Juniors and we were given our own hymn books... I still picture him thus!
