I thought the boat set out from the river Sal as well. Just before the boat first came into shot you could see a couple of local boats moored by a bar painted in Bello beer colours. This to me looked like one of the bars you pass by on Bettys boat trip up near the ferry crossing point.
Plenty of good street shots in Delhi and Agra. Anyone who has been to Delhi will reconise the location of the final scene at the Red fort with Esther walking off up Chandri Chowk.
You pass by Gurgaon (the setting for the climax of the play) which has been pretty much built up round the call centre industry on the road between Delhi and Jaipur.
