Richard,
I think that I see what the problem is.
I followed your link and quite rightly, you clicked on People and then typed in Gordon Hall which brought up our wonderful singer and all the references to him. However you can't see all the songs and articles about him because you still have People clicked and the way the search engine is programmed, it still thinks that is what you are searching for.
Try clicking on Records and search for Gordon Hall and you should be able to access the 330+ references to him on the database.
That works for me but please let know how you get on and if it doesn't work, I'll see that it is fixed.
