Visiting every tube stop in Zone 1

Ewan, a Scotsman living in London, is moving back to Edinburgh, and before he does, he has resolved to visit every tube station in Zone 1, and he's inviting the general public along on his tube-crawl:

Here's the deal, I'll be starting at 12.30 on a weekday in the last week of July (probably Friday the 30th July, but don't quote me just yet). If you'd like to join me as I rattle round Central London and visiting every station of note (and Hyde Park Corner) then make sure you're at Vauxhall Ticket Office for around 12.20 to find me.

Anyone wishing to set up a Rival team to try and beat me on the day is more than welcome, I'd only ask you to also start at Vauxhall with us. Once it's all over, we'll retire to a pub at around 4pm for a late lunch/early dinner, some farewell drinks, and I'll invite you all to the housewarming in Edinburgh.

Update: Quin sez: "I'm visiting every tube and train stop in Zone 6, saying what people can find there, who lives there and how to get back. "
