I have another anecdote herard from Mukhi Shamshu Murji who was Mukhi of Shinianga Jamat in 1966 during Didar and who lives in Toronto [Etobicoke JK] - he has the names of all the people involved, unfortunately I don't remember.
One day Prince Aly khan took the stearing of the car to go to Mwanza. One person sat in the front near Prince Aly khan and 2 sat in the back of the car. The road from Shinianga to Mwanza was full of bumps and pot holes at that time so one of the person sitting in the back said in Katchi to the person sitting near Prince that because the Prince has a very speading driving, please when there is a big bump coming, just tell me "Acheto" [It is coming] and I will hold my seat.\
It so happen that Prince Alykhan was driving so fast that before the person in the front could inform the persons in the back of the coming bump, Prince Alykhan shouted"Achetooooo!!!!"
