I've been busy tidying up the code on the music pages, getting rid of unwanted out of date data. I've placed all further information on a secondary page with links between at the top.
I've added navigation guidance on the Help page and filled out pages on the ABC Song pages.
The menu bar on the left can be collapsed and this may be particularly helpful on the Songs pages, as it will show the music Full-Page.
The layout is fully responsive with the menus being available from icons.
