Both of my children and my 2 nieces loved this book. We took them to a workshop that Michael did at the National Theatre back in the '80's. The song has become an anthem in our home. Now my 2 grandsons enjoy singing the song and reading the book. When I was a supply teacher I taught to the younger classes that taught and when I had my own class. When I taught in New York I shared it with the children also. It's frequently requested by the children I teach when we have time for a sing a long. I took my eldest grandson to the show when he was younger and he loved it. This story is a classic and I feel honoured to have been taught the song by the author 30 odd years ago.
