Anna McNay: In the foreword to your book, Going Underground, you pay tribute to the influence of Walker Evans and his New York subway series from the 1930s/1940s. It has been said of Evans’ work that the subway might be seen as a “prime symbol of urban life.” What does the London Underground symbolise for you?
Martin Davey: Yes, Walker Evans comes from an era of photographers I have been heavily influenced by. I wouldn't disagree with that statement, but would add to it, because today the Underground is also a great example of cultural diversity, a showcase of how multicultural London has become. It’s the lifeblood of the London transport system, and it’s what keeps London buzzing. I love that buzz.
