And then there are a variety of English accents variations all across the UK plus the Scotts and Irish.
And don't forget the rest of the Commonwealth nationalities. Here on the US West Coast late evenings we get the Kiwi's and the Aussies on too.
I once saved my wingman from asking if a friendly pilot on range was from Australia, and interrupted him, as clearly (to my ear) he sounded like a Kiwi. Instead I said it sounded like he was in New Zealand, and the Kiwi guy was impressed I spotted the accent. I've traveled a fair bit and have developed a good ear for accents. I can often tell what US state someone is from. I asked a new squaddy what part of Canada he was from and guessed Toronto (correctly).
My favorite case of accent spotting was identifying two Geordies in an airport bar in Dulles International. They were trying to order a Shandy and the bartender had no idea what a Shandy was and was telling them "we don't have lemonade", which baffled them. I had to explain that "lemonade" in England means Sprite or 7-up soda (pop, if you're midwestern).
The two Geordies were appreciative and each bought me a round, as was the bartender for educating him, who bought me a third. Drank for free during that 3-hour layover.
Having a good ear for accents pays off sometimes.
