Sometimes, one thing is such a memorable, representative example of a group that the entire group comes to be known by the same moniker as its most-famous member. Like Star Wars. Or crock pots. Or xeroxing.
Or this, Haydn's London Symphony. The last ("and best," he says, as if it's actually possible to make that kind of judgement) of the dozen London Symphonies. Enjoy!
