It was around 11:30 in the morning of the 8th August 1969 when Iain MacMillan took a photograph of John, Paul, George and Ringo crossing the most famous pedestrian crossing in London – and probably the world. This was in Abbey Road just outside the studio where the Beatles made their records. It remains one of the most iconic album covers of all time and is imitated by around half a million people every year.

Chinese New Year has arrived and as London celebrates the Year of the Dog with the biggest Chinese New Year celebrations outside of Asia, my thoughts turned to this city's longstanding love affair with man's best friend, the dog. There's a lot of puppy love in the Great British capital - a phenomenal 200,000 dogs and counting call London home.  That's almost twice the size of the population of Reykjavik!
