When I uploaded this previously, I attributed the performance to the wrong Christopher (bad note-taking on my part).
This performance of Olivier Messiaen's "show-stopper" is by Christopher Herrick. It was recorded in 1969, before the massive Noel Mander re-build of 1972-77.
This is probably Messiaen's most popular organ composition, although he might have cringed at having any of his compositions called "popular" ;-)
