I invite you to freely partake of much of my wassail research here and spread the tradition to all!

I also have published a comprehensive hymnal- nothing worse than people turning up who dont know the songs (most of them)

Each purchase keeps our reference page going. we are not on any grants.....

Enjoy and spread the word freely.
