Funny, I'd never thought I'd end up busking on the underground.

I'd already picked up a couple of cheeky pennies early on, when I came across a charming girl who was tinkling the ivories on an electric piano. She was playing some fiendishly tricky Frederic Chopin (Polonaise).

Attempting to sharpen my chat-up skills, she foolishly allowed me to have a go, and I was able to attempt the simple chop-sticks (rather than Chopin) that we were banned from playing at school.

Needless to say, no money was forthcoming.

However, as I passed an empty busking point in Covent Garden, I did pick up a couple of silver coins (5p and 10p) that a former artist had overlooked.

I did find some wonderful antique silver in the Covent Garden Market, a map, emblazoned upon a fossil, a piece of one of Concordes's engines, and a small car.

It's amazing what you can find if you keep your eyes open.
