This is an adapted version of Lewis Carroll's famous story (public domain). The play is suitable for performing as a school show. There have been some suggestions for suitable songs within the script but please ensure that no songs are performed without first ensuring correct performing rights have been covered/not required dependent on your region/country.
This could also work as a play rather than a musical.
Lots of parts available and chorus could be as small or large as necessary.
A fun and interesting script with lots of scope for a school to perform as it suits.
