I haven't been to a huge amount of live entertainment, thus far on my trip. But tonight, I was in for a treat: Max and Joel took Jack and myself out to a club in London's West End, which is famous for its all-star line-up of Monday night jazz music. Apparently, the place is crowded and sleazy (and the music sucks) on other nights. But every Monday, they have this setup where a great band — comprised of some of England's best-known jazz musicians — play for an hour or two; and then, they hand over the floor to amateur musicians, which is anyone who's walked in the door (with their instrument, preferably), and who is willing to get on stage and to join in, improv style. No cover charge, either. This is a great show, and it's also clearly a huge opportunity for aspiring musicians to get themselves heard. Anyone's welcome, but the night is certainly first and foremost "by musicians, for musicians".
