Thanks for the suggestions.

The Child List includelet has worked well to show the Show Results.  It's actually better than the original 3 level structure.  Having looked into these, I can see that the Child List includelet will be useful elsewhere.  I hadn't realized its potential before. 

Thanks also for the topics demo'd at the last zoom meeting.  I was able to use the grid structure and buttons to point to the Spring, Summer and Autumn Shows on the hidden level 3. It also looks better visually.
