 This is about a five-year project to completely rebuild and renovate the cathedral organ. Kevin Ekstrom, chief public affairs officer with the National Cathedral, says it needed to be done. At least a quarter of the organ was no longer functioning properly, and now crews are working to completely dismantle it. They had to build this scaffolding that we're standing on 40 feet above the ground, and then the process of removing 10,600 some odd pipes. The organ was originally installed back in 1938. Tom Sheehan is the cathedral's organist.
