Priest Roly Bain, who died last year, was succentor at Southwark Cathedral before serving in Southwark parishes and later also becoming a clown.
The appropriate date recalls that Roly often spoke of 'the feast of fools' and holy fools speaking truth to power.
In 2014 he said: "The church takes things too seriously sometimes. There is a very old tradition of clowns or jesters in church and they can symbolise comedy and tragedy. I try to fit in as many messages as possible because I am doing Godís work ultimately."
