Through my research at the fantastic Tower Hamlets archive (worth a visit just to see what deceased library looks like - you walk through one to get to the loo!) I've been finding out a lot about the history of the 'Jago' (slum that pre-dates the Boundary Estate) and the Circus itself.

The best thing we've found is this list of the residents occupations before the estate was built. Unlikely as this may seem it formed the basis for our 'musical' experimentation this Monday evening (we're currently a 'song' in search of some sort of lyric) and was, I thought, surprisingly successful!
