Anne Of Green Gables – The Musical is a musical based on the 1908 novel Anne of Green Gables by Lucy Maud Montgomery. The book was written by Don Harron exclusively, the music by Norman Campbell and the lyrics in a joint venture by Harron, Norman Campbell, Elaine Campbell and Mavor Moore. It has been Canada's longest-running musical, performed annually from its opening in 1965 until 2019, with the planned 2020 and 2021 productions cancelled due to the COVID-19 pandemic. In March 2014, it was officially recognised as the longest running annual musical theatre production in the world by Guinness World Records.
