In acknowledgement of Stow's continuing reputation as the founding father of London history, the quill held by his effigy has been periodically renewed. The renewal is mentioned as taking place "annually" in 1828; and, although the custom may later have fallen into abeyance, it was revived following the monument's restoration by the Merchant Taylors' Company in 1905. In 1924, the ceremony was incorporated into a special church service, with an address by a London historian; and this service continued to be held annually every April until 1991, including the years of the Second World War. No services could be held in 1992 or 1993 because of damage to the church caused by the Baltic Exchange bomb of 1992. The service was revived in 1994, but from 1996 to 2017 was held only once every three years. The service due to take place in 2020 was cancelled because of the COVID-19 pandemic. The services are jointly sponsored by the Merchant Taylors' Company and the London and Middlesex Archaeological Society, with the quill supplied by the society. The exchange of the quill is undertaken by the Lord Mayor of London or the Master Merchant Taylor alternately.
