I've realized that I forgot to include something we saw in Brighton that was really fun - in a street blocked off as a pedestrian mall, they had a street fair. In the course of one block, I counted:
Two lightning caricaturists;
One portrait artist (chalk);
Two Tarot readers; and
One elderly Oriental man doing chair massage.
This was in addition to the usual collection of people selling bead jewelry off quilts on the sidewalk. It was a lively and very urban scene; I can't recall the last time I saw street artists (as opposed to graffiti taggers).
