For what it's worth, I've heard a fair amount of classical music over many years, I would be surprised if I could put a title to 5% of it. I'm old enough to know Ravel's Bolero from Torvill and Dean and I'm sure I'll have heard Vivaldi's Spring but wouldn't be able to put a name to it, the other one I know nothing about.
