The SW12/SW17 Neighbourhood Network published a delightful walking trail from Balham to Tooting a few years ago. The walk takes you from Balham Station to Tooting Bec Underground.
There is an accompanying soundtrack where you can hear memories and reminiscences of life in Balham and the characters who live and work there. They include comedian Arthur Smith, local shopkeepers and local residents.
You can download the whole recording from the link below.
