St Magnus was one of the churches that held special services before the opening of the second Anglo-Catholic Congress in 1923. Fynes-Clinton was the first incumbent to hold lunchtime services for City workers. Pathé News filmed the Palm Sunday procession at St Magnus in 1935. In "The Towers of Trebizond", the novel by Rose Macauley published in 1956, Fr Chantry-Pigg's church is described as being several feet higher than St Mary's, Bourne Street and some inches above even St Magnus the Martyr.
