This one's mainly for the Aussies, as I'm not sure they are made elsewhere, but does anyone remember their Sing books?

I was doing some sight reading practice tonight using mum's old ones, and it occurred to me just how many great songs they have in them.
Anyone collect them or anything like that? I didn't count but it looks as if we have about 40 of them. I think we have all the years but 2 or 3.

I LOVED the Sing books! It was one of the higlights of the new school year I've got one laying about here somewhere but I wish I had kept my old ones from school.
