I do not know. Says the great bell of Bow

The great bell of Bow refers to the church of St Mary-Le-Bow on Cheapside. There has been record of a church at this location for almost 1000 years. Another design of Sir Christopher Wren, this church is considered to be one of the most important in London, after St Paul's Cathedral and was as a result one of the first to be rebuilt after the Great Fire of 1666.

The great bell of Bow is said to have convinced Dick Whittington to return home by telling him that he would one day become mayor. Dick Whittington was a real historical person and was made mayor 4 times. Also, only those born in hearing distance of Bow bells can call themselves Cockneys.
