A stone arrow in the sky. So easy, from the station, to spot Saint-Théodule. Push the door of the temple. Vast nave and colonnaded galleries. And then, suddenly, the organ that fills choir and heart. The musician up there welcomes you. There Toccata and Fugue in D minor of Bach? I’Merry not much anymore of Beethoven? No. It’s an improvisation. An exclusive, therefore.
